MyBB Community Forums

On my forum, posts have started acting up.

Mark all as read no longer works without hard refreshing and even then sometimes it will start marking forums as having new posts when there haven't been any recently. Or, when I try reading a new post it won't show anything new without hard refreshing.

I don't know if this is more of an issue with myBB or my host but I'll ask just in case here.

Thas a jQuery issue i suppose.
Did u install any plugin before everything as you said had happened?
and please post your forum link

I didn't install any plugins between the time of the issue and now

As envira asked, what is the URL to your board?
