Thread:Project:Support desk/everything is broken

Dear Support Team, We have migrated our MediaWiki to another Server. Now it is broke completely.

This is what I did: dumped Database - downloaded directorys and files - uploaded directorys and files - uploaded Database - changed LocalSettings.php

the URL of the Wiki is fcnwiki.de

When I try the /maintenance functions, like rebuildall.php I get the Warning: Warning: fwrite: supplied argument is not a valid stream resource in /var/www/web0/html/wiki/wiki/includes/Exception.php on line 172

Permissions for Dirs and Files are set....

I dont know what to do right now and I hope you can help me. Thanks in advance, C.
