Could someone explain how to fix this error? I'm starting to see this on my mediawiki site. As an example : From http://asianmediawiki.com/SP is you click on any of the cast member pages it produces this error message: Database error A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "Parser::replaceLinkHolders". MySQL returned error "1271: Illegal mix of collations for operation ' IN ' (asianmediawiki1.asianmediawiki.dreamhosters.com)". Except for person "Taro Omiya". Anybody could provide clues on this problems? Thanks
