Forum and admin say a update is running
It has been slow for days, partly because bots were performing Zlib flushing.
But after resolving that problem, the forum remained slow.
So eventually I decided to restore a server backup, and lo and behold, the forum turned out to be faster as a result.
But suddenly the forum was gone with the message that an update is running. I get the same message in Admin as well, and because of that, I can't click on anything anymore!
Is there any way to restore the forum to its original state?
