Hello, every 4 hours the file /var/lib/mysql/xxx.err reports this error: What is the folder roundcube_bk? Can I delete or re-create it? How can I fix this? thank you.
I solved the problem. I deleted .frm files for each individual error. Now /var/lib/mysql/xxx.err does not report any error. I hope that this solution can help someone with the same problem.
Hello I'm happy to see the issue now resolved. Note that you can typically remove the database through the MySQL command line if it's not an active database on the system. It's possible that roundcube_bk was a leftover roundcube database that was previously backed up. Thank you.
