Can you please tell me how I can adjust this ? or do i need to update it for this not to occur anymore.

I have  customer that says that forums is not remembering the last posts his read on the forums. So if he logs onto different computers the information about what he has read is lost.  

Is their a setting i need to adjust ?

The unread posts since your last visit feature is exactly that. It shows you what forums and topics contain unread posts since you were last on the forum (forum session)

This is useful as many people especially on busy forums just want to know about forums and topics which contain new posts.

If you log out, close your browser, have 20 minutes of no activity, login on a new computer, then a new session will be started and the unread posts will only show posts that have been created since your last visit (session).

So are you saying that when I log into a different computer (2nd computer) .. and 20 minutes have passed .. all the read posts that were processed in my previous session (1st computer) should remain as read ..

My customer is saying that this is not the case .. as soon as he logs onto a different computer the forum forgets the read posts from previous computer.  The session should be controlled by the central server not a users PC.

I don't know if you are simply not understanding what I am saying or I don't understand what you are saying, or we are both taking about different things.

Could you please explain the issue more fully as to what exactly the issue is and steps to replicate it?

Funny, I just had the same "complaint".
A forum member is at work, logged in and reading messages from his work computer over his lunch hour. That's computer 1. At 2pm, he logs off, then at 4 he drives home, logs in on his home computer, and what he sees are messages since his last stint on THAT computer, his home computer. Not since he was logged in and reading at work. So he sees messages that were new since last night, not 2pm that day when he read them at work.
I've seen similar - it looses track between sessions - suddenly I find that I am being shown messages since "last night" not since 4 hours ago.
It usually works for me, but I check between 3 different computers and if I log out of one at 4pm, the log in an hour later at home, it NORMALLY shows me messages since 4pm. HOWEVER, at times, it shows me messages since my last login on THAT computer, not since 4pm, or even "yesterday". somehow these are getting lost......
I've found that if I am logged in, and then I find myself suddenly logged out (it happens a lot) that when I login again, I get no new messages as it shows since the time I was kicked off. I think at least once every two days or so, sometimes 2 or 3 times a day, I get logged off through no action of my own, and it totally messes with the "last visit" times.

There are two ways that the last post date is calculated. The first is through a cookie stored on your PC which stores the last date of your visit on that computer, this is for people who are not logged in or members. The second is by your last visits stored in the database under your account. Once you login the last visit date is updated with that stored in the database.

Your member once logged in and refreshes his page will see the last visit date update so that unread posts will be calculated from this date.

If you find you are having issues with staying logged in or incorrect last visit dates then you should make sure cookies are enabled on your browser and if still having issues clear out your cookie cache.

If you are using multiple computers then when you move between computers you should always logout and then login on the new computer.

This way the forum will be able to get the last active date from your account in the database rather then the cookie. This should make the unread/read post data more accurate as this uses the last active date to collect the data.

I've raised this issue with a (recently) created forum as IMO its making the site almost unusable. I'll try the logout/login suggestion but its a PITA.

I'm hoping the makers of WizWeb can see this as a bug (or at least provide an option to address it). I'm not sure why there is a need to have two seperate time login sources (server and cookie?). And if there has to be, then why the server timestamp doesn't take precedence over the cookie timestamp?

The last visit date is stored in a cookie so that for members who do not login or people who view the forum as guests also have the option of viewing new posts since their last visit as well as having the read/unread posts feature.

The read/unread posts feature is always going to be a 'best as compromise' feature rather than being 100% perfect due to the way HTTP sessions work. The only way to make it 100% perfect would be to store the data on read/unread posts in the database, but then your database would be enormous with all this extra data, web hosts would be kicking you off for using 100% CPU load, and you would be complaining that pages took 10 minutes to load.

There is an issue with the read/unread posts system if you move between computers which is being looked into to see if any improvements can be made.
