MyBB Community Forums

Hi,

did a fresh install of mybb 1.6.4.

The problem I got is that for all users once they log into their accounts, all topics are shown as unread (even though they did read them before).

Once they enter one of these topics and then go back to the forum, then ALL of topics are shown as read (even though only one of those "unread" topics were checked).

If you log out and then log in, then everything is shown as read.
However, if you clean browser cache and cookies and then login, everything is back to the situation I described (all topics unread, then all topics read when you visit just one topic).

It seems like read/unread statuses are saved in cookie/session, not in DB.

Any idea what to do to fix this?

Found the solution myself.
Apparently I misread this option:
Read Threads in Database (Days)
The number of days that you wish to keep thread read information in the database. For large boards, we do not recommend a high number as the board will become slower. Set to 0 to disable.

I thought that 0 will mean no days limit at all (in other words, it would work like 99999999999999).
