Hi there,
I've updated my server to the latest php and mysql versions, all my websites and scripts works well except MediaWiki which shows none of articles regularly (editor shows them properly, then they are there in DB). I read about the problem across the net, and it seems that the only solution is upgrading. The thing is my MediaWiki is widely customized (even plugins and theme), then the upgrade is a useless solution. Is there any other solution (like changing a line, adding a code, replacing a file) to solve the issue of empty pages?
