Well, I finally found a server that would reproduce the “Illegal mix of collations” error that MySQL troughs when executing some queries in my TERRIBL Plugin. See, I guess alot of servers use latin1_swedish_ci as the default collation for their MySQL databases. This seems to cause an error in some queries, especially those that use foreign characters. So I have patched my Plugin by explicitly setting all my database collations to utf8_general_ci. I also added an error handler that looks for this error in database table that may have been created by older versions of the Plugin and the new version will now fix the old tables using an “Alter Table” statement. So upgrade to version 18.104.22.168 now.
