Thread:Project:Support desk/Upgrade from 1.11 to 1.22 : Blank Page & Nothing can be seen

Hello,

I am totally new to MediaWiki and I'm working for a friend on upgrading his system. He got it installed by some guy before and is totally out of Tech talk .. Anyway, I just tried several times upgrading using the method of downloading the 1.22 version, uploading it over the old 1.11 version after a database and files backup. All done but once everything is uploaded, I just see a blank page and LocalSettings file dissapears for some reason once I upload the 1.22 version (even if it doesn't contain one, it just disapears while the 1.11 one should be there ..).

I tried even uploading the old and a new LocalSettings file with error reporting toggled to 1, no results. Update.php file also returns a blank page. Here is the URL : http://azrai.com/wiki/

Please help ! Thanks
