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

Hi Marcus,

Debian 7 does have a current PHP version, 5.3 or newer, right? Then this should be fine.

You say you copied the image directory. That is fine, but not enough: Also copy the extension/ directory, if you use any extension (check LocalSettings.php). And if you modified the skin or use your own skin, then also copy the folder skins/. Maybe you still have some old cache files (MediaWiki cache, if activated, PHP accelerator, if any); those should be removed. The symlink should not be necessary then.

You say you get a 500 server error when you upload files and when you view files. When you view a file you get the error when you click on the link, which points to the file directly.

That can have different reasons. Check the Apache error log - there you will find more information about the exact error.

For the missing thumbnails: This can be caused by a missing library, e.g. here it was Libjpeg, which had to be installed.
