Thread:Project:Support desk/Wiki page Log in brings up 500 error/reply

I just tried accessing your wiki: Viewing pages works, but you cannot try to edit them. This gives an error 500 as well.

You can view e.g. the page "Recent Changes", but when you click one of the options, e.g. to see more changes, then the resulting URL http://www.wikazine.com/w/index.php?title=Special:RecentChanges&limit=500 does not work.

It looks like all URLs starting with http://www.wikazine.com/w/index.php do not work. The problem might be somewhere in your configuration of Short URLs. It would help, if you could have a look at the Apache error log; it should contain information about the error.

You say you did an upgrade to 1.20.2. However, your wiki still displays MediaWiki 1.17 as the version you use. If you want to do an update, that is fine. Do not forget that you then also have to update the database! You do not have to log in to do that, just run the maintenance script update.php or use the web updater, which you can access with your webbrowser.
