blown_dry Guess we'll see if this reply works... Also tagging Bessie and Juliarugula to see if that's working.
I ran the OS and application updates and, yes, restarted the server. The server had been running for 99 days.
There is a major OS version update available but there will need to a little more preparation put into doing that.
Also, cleared the forum's application cache.
If there are still problems, I'll look at updates to the forum software itself.
