Also some guesses from my site:

You say you have updated MediaWiki and then the problem occurred. From which version did you upgrade? Was it a really old one (like 1.4 or 1.5 or so)?

Have you also changed something else? Have you e.g. updated the MySQL version? Or moved the database to a new MySQL server?

Have you maybe changed some configuration setting in LocalSettings.php, e.g. the value of $wgDBmysql5?
