Title: "Show unread posts since last visit" not working
Post by: Mike on Dec 14, 2007, 19:16:51
My "Show unread posts since last visit" button is not working.

When I press it I get that there are no new messages and yet when I check the forum I see lots of new messages that were posted since my last visit. This happened in work and again now I am at home.

Anyone else experiencing this?

THis is still happening to me. I can clearly see new posts posted today and yet the "Show unread posts since last visit" produces no results.

Post by: Ian on Dec 24, 2007, 12:17:30
I've got no idea what's causing this, I'll have to do some research. I notice that sometimes the "new" icon is missing from new posts. Might be related.

Just curious, what browsers are being used ?
I am using IE7 and amongst other things, I have noticed no "new" buttons, occasional display not as "frames".
I have only just found the "unread" button, so can't comment.

I get the same thing on IE7, Firefox and Safari.

Still getting this also. Ian's posts on the "Uhoh" thread were not coming up when I pressed the button, but could be manually seen in the list.

Mike,

does the new post notification emails work for you?

Be aware, straws are being clutched at, at this point...
Title: Re: "Show unread posts since last visit" not working
Post by: Mike on Jan 03, 2008, 11:24:22
Never tried it as I didn't want to be spammed. Have just set it up (irritating as you have to do it 10 times, you can't do it for the entire forum that I can see). Will see how that goes. However, it's not what I want as I access the forum from work and home so emails will only go to one location. The "View unread posts" button always used to work fine until fairly recently.
Title: Re: "Show unread posts since last visit" not working
Post by: Ian on Jan 03, 2008, 12:33:20
I just want to try and establish whether it's something the bbs system isn't doing properly internally (email notifications don't go out properly) or whether it's a cookie problem (tracking what posts you read and what's new). Do you get the same behaviour at home and at work?
Title: Re: "Show unread posts since last visit" not working

Show unread posts buttons works OK for me..... John
Title: Re: "Show unread posts since last visit" not working

Yes I get the same behaviour at work (IE6) and at home (Firefox and Safari)
Title: Re: "Show unread posts since last visit" not working
Post by: Carole on Jan 04, 2008, 17:08:25
I Looked at about half the "show new messages" today and it worked OK.
I've just gone back in to view the ones I did not have time to look at before and the whole lot has gone.
I DIDN'T accidentally click on "mark all messages as read" either.

So "you are not alone Mike".

Very annoying.

I haven't received any emails notifying me of new posts either so that bit doesn't work too.
Title: Re: "Show unread posts since last visit" not working
Post by: Ian on Jan 04, 2008, 18:59:42
actually, I think this might actually be working correctly, but not the way we're thinking it should. It's new posts from your last visit, rather than showing unread posts. I need to read up on how and what it does before I do any more poking around.

No emails either Mike. Hmm, something else to think about...
Title: Re: "Show unread posts since last visit" not working

Post by: Carole on Jan 05, 2008, 10:57:47
Hmmm, Now I've read Ian's reply, I think it is my brain not working, rather than the "Show unread posts since last visit".  I was thinking it was just "show unread posts"

Incidentally that would be a useful feature as on the basis of my experience yesterday and not having the time to read them all at one sitting having been away.

That is exactly how I thought it was meant to work. I log on after a day or two and there are lot sfo new posts, that can clearly be seen manually on teh fron tpage, but teh "SHwo unread posts" button produces nothing.

it does appear to be flaky even once it's understood what it's supposed to do.

It's almost certainly that the forum is getting a brief glimpse of you and thinking that you've visited it more recently than the last time you actually gave the forum any attention.
Title: Re: "Show unread posts since last visit" not working
Post by: RobertM on Sep 15, 2009, 09:57:26
Ditto here too.  There is nothing consistently wrong but I'm finding that posts are definitely being missed.
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Sep 15, 2009, 10:42:26
I can think of situations when "Show unread posts since last visit" will miss posts, depending on what sets the "this is when you last visited" time. Consider the following sequence:
My guess is the next time you click on "Show unread posts since last visit" it'll use the *:05 time, and miss the *:03 post...

On a quiet forum when there's seldom more than one person online it'll work fine. If there're a hundred it'll be not much use. I rely on the main indexes...
Title: Re: "Show unread posts since last visit" not working
Post by: mickw on Sep 15, 2009, 11:58:02
Perhaps hitting "Refresh" before you quit the current session ?

OK, that's not the answer  :-?
I just quit the forum with no new posts visible, then restarted and there were "new posts" showing in the section headings.
I had a nose around the sections and read the new ones but I didn't notice one of them  :oops:  When I went back to the main menu and hit Refresh, there were no new posts showing under the sections but when I clicked "Show unread......" the one I missed showed up.

Don't know if that helps or confuses things more  ;)
Title: Re: "Show unread posts since last visit" not working

It seems there's also something odd that happens if someone edits a post. Not sure exactly what, though...  :roll:

show unread posts since last visit and also "Click here to try all unread topics."

dosent seem to be working today.
well at least from about 3pm anyway.

Mac.
Title: Re: "Show unread posts since last visit" not working
Post by: Carole on Nov 15, 2009, 21:32:06
Mine hasn't worked for a couple of months.  I've given up now and just look for the blue tags.  It does mean I miss the odd post now and then though.

Post by: Ian on Nov 16, 2009, 10:59:47
it's probably worth avoiding the "back" button too. Lots of the forum is clickable (for example Orpington Astronomical Society > Random Rambling Ruminations > Updates and Upsets > in blue above will take you back to the forum you came from. The browser will then give you a fresh impression of the page with any updates that have appeared in the mean time.

This is still not working reliably and I keep missing important posts.  Is this something to do with my PC settings and if so, what should I do?

Carole
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Jan 13, 2010, 16:29:07
It is known not to be 100% reliable because it uses a very simple mechanism which cannot catch everything.

Quote from: Carolepope on Jan 13, 2010, 15:51:42what should I do?

I would suggest not relying on it, at least for important messages (whichever they may be).
Title: Re: "Show unread posts since last visit" not working
Post by: mickw on Jan 14, 2010, 10:21:07
Just curious, are the read/unread flags generated by cookies ?

A lot of people have reported this problem so it's either a forum issue or something our systems are doing.  A common thing we do on our PCs is delete cookies or prevent them.
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Jan 14, 2010, 19:06:13
The forum does use cookies, but only (as far as I can tell*1) for login. It may get confused if you delete cookies while you're reading the forum.

There is a database table keyed on user and board IDs with a field for message number. As far as I can tell it's a "low water" level rather than a post-by-post one*2, but it might be trying to be a bit cleverer than that so that some holes in your reading history survive for a while.

One thing it might be worth trying is making use of the "Mark All Read" option occasionally, as that'll make sure it has a clear line to start at.

Also, if you have a category hidden (aka "collapsed") then you may well not see any new posts in it*3.

Obviously, if (for some reason) you're not logged in then the forum won't adjust (or use) your last visit pointers.

*1 It's possible it might use cookies to get a "last time I visited" value, but the experiments I've done suggest that it doesn't.

*2 A post-by-post table would, of course, get stupidly large very quickly...

*3 There's a hideous join in the query that determines what's read and what's not read which includes invormation about hidden categories.

Cheers Rick

Looks like it's not an easy fix after all, shame  :(
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Jan 15, 2010, 00:10:55
I think it tries to keep some sort of track of holes in your reading, so that it can flag as new posts you've not yet read, even though they're older than posts you have read. However, I suspect it doesn't always succeed.

I suspect it does suffer a bit from the window of missed opportunity problem I described earlier.

If you make much use of the (http://forum.orpington-astronomy.org.uk/Themes/oas/images/expand.gif) and (http://forum.orpington-astronomy.org.uk/Themes/oas/images/collapse.gif) buttons then I think you'll probably also increase your chances of missing something.

So, in summary:

I've been trying to spot a pattern, but so far the only time I think I might have caught it not showing all the unread messages has been when I returned to a tab which had been sitting open but unattended for a while.

Carole
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Jul 06, 2012, 11:19:48
Yeah, which makes it trickier to track down. I suspect it gets an updated last-visited time, and misses all the new posts in a particular time window, but it's hard to reproduce the circumstances...

Post by: Carole on Jul 06, 2012, 16:48:20
Now for instance I just came onto the Forum and it showed me the post about the Weather, are the weather God's joking?.  But it wouldn't show me this post which I found because it was in blue.

Carole
Title: Re: "Show unread posts since last visit" not working

So you are saying that you can see "new" posts that have the blue "new" tab but not the "recent posts" list at the bottom ?
Title: Re: "Show unread posts since last visit" not working
Post by: Rick on Jul 06, 2012, 18:42:55
Hmmm... So it missed the older of two posts, which fits my speculation but isn't conclusive...
Title: Re: "Show unread posts since last visit" not working
Post by: Carole on Jul 07, 2012, 00:19:51
No Mick, when I click show unread posts it might list say two, but if I then look down the list of sections there could be several new ones highlighted in blue which I haven't read which haven't come up on the show unread posts list.

Title: Re: "Show unread posts since last visit" not working

If you un-hide the stuff at the top (click the (http://forum.orpington-astronomy.org.uk/Themes/oas/images/upshrink2.gif) on the right-hand end of the line that says "Hi Mick") you'll find some links inside. It's one of them. Usually, I leave all that stuff hidden as it uses too much screen space, and look for blue logos instead...

I suppose you could bookmark the relevant link (http://forum.orpington-astronomy.org.uk/index.php?action=unread), but it does occasionally seem to miss a post or three...

Carole you are replying to a 10 year old post. The entry before yours was by Mick, in 2012.

Is it response to that post or a new issue with unread posts?
I've not noticed any issues and ive always used unread posts as a saved link.

The answer to the issue is probably in this earlier post in this thread (http://forum.orpington-astronomy.org.uk/index.php?topic=2833.msg33101#msg33101).

Basically, that feature works best when you keep things simple, and is apt to get itself in a knot if things get complicated...

What on Earth does that mean?

I use the forum exactly the same every time.  I click on Unread posts and normally it shows me posts l haven't read. 

The last few days it is not doing that.  What is complicated about that?
