Thread:Project:Support desk/500 Internal Server Error after Migration/reply (3)

Hi!

If MediaWiki does caching can be seen in LocalSettings.php. If you do not have settings about that there, then the default is valid, which should be: No caching (at least not to files). There will also be entries in the database table "objectcache", which you can truncate. However, these entries should over time also be removed automatically by MediaWiki and I don't think these cause your problem.

I don't get the picture problem currently:

You say you moved the files from /var/www/ on the old server to /data/www/ on the new server. And on the new server, they are also in the correct folder? Meaning: The structure inside data/www/ is correct? Images not by accident put into a subfolder or so?

This all sounds as if you had an old, absolute path hardcoded somewhere in your files. Please check, if you still have /var/www/ anywhere in your MediaWiki files!
