Today, I encountered a strange issue with my XenForo installation.
I was trying to rebuild my user cache and ran into this error. Thinking it was related to an add-on I was using, I tried disabling the add-on and received this error. I then tried disabling other add-ons and received similar results.
To say the least, I am a little confused. To begin, I've done a little diagnostic information on my end. Thinking there may be a corrupt MySQL table, I tried checking, repairing, and optimizing my MySQL database for XenForo by following this guide. This is the exact command I ran:
# mysqlcheck -u root -p --auto-repair -c -o xenforo
The next thing I tried was restarting the MySQL server, but that also did not help any.
I am quite confused… any help would be very appreciated!
