if any member make an post to an Thread and i want to watch them
i see myselfl logged in as the User which posted the post but cant see the Post and if i want to reply
i get this error

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.
and if i clear my cache or press f5 + ctrl its working fine
and if i switch to vbulletin default style on main site style is working and if i want to watch an new thread i see the old style and that bug and in footer the time is incorrect
any fix for this ?

We are having the same issue. Not sure we have all those security features in place. Certainly not hidden IP addresses. It happens when we mark all threads read

<a href="{vb:raw $vboptions.vbforum_url}{vb:if "$vboptions['vbforum_url']", '/', ''}forumdisplay.php?{vb:raw session.sessionurl}do=markread&amp;f={vb:raw foruminfo.forumid}&amp;markreadhash={vb:raw bbuserinfo.securitytoken}" rel="nofollow" onclick="return mark_forum_and_threads_read({vb:raw foruminfo.forumid});">

Can't use the modification from 3.8 Not sure what to do about this error... vB tech is stumped.
There was a fix for v.3.8 but doesn't seem to be relevant to v 4. https://vborg.vbsupport.ru/showthrea...91#post2420691
