Marking Forums Read And Other Sudden Glitches
 

Running 3.8.7 on Tapeheads.Net.

Just yesterday, a problem has surfaced. And that is when I click "Mark Forums Read" instead of doing that I am taken up to the top of the forum. I click on 'New Posts' and all of the new posts that I thought I just marked 'read' are still there. Normally I would get the "No New Posts" message (unless a new post was made in the intervening few seconds). But when I refresh my browser, then all of the "new" posts will disappear. I will then select "New Posts" a short time later and I will get the screen that shows any new posts but also older ones separated with the The threads below have not been updated since your last visit but still contain unread posts message. This is also a new glitch and the site has never done this before.

One of my Mods has reported "I click on unsubscribe in my thread subscriptions list and the screen refreshes and the thread that I unsubscribed from is still there. Also, I reply to a thread and instead of going to the top of the new posts list, it disappears."

I have confirmed this on my end using both IE and Firefox. I have cleared out all history. And I have not installed any downloads, patches, etc nor have I done anything with the templates.

The issue has simply appeared out of the blue. Any idea what the cause-and more important-the fix is?

Please explain it as simply as possible. I am not at all skilled in reading, writing, or interpreting code, html, etc.
