Apache failing for MediaWiki - apache

Question

I have made a mistake while editing config files (new kid on the block). But now our Mediawiki is not being displayed anymore correctly. The page will load but it will display akward, and the normal formatting is gone.
The page it self is white and missing all kinds of formatting
Hyperlinks are being displayed in blue, which have not been clicked
Other hyperlinks that have been clicked are being displayed in purple
Titles are being displayed in black color
I assume the error is within 000-default.conf. I tried to find the error and correct it my self but I have come to a point whereby I really require assistance. So I was hoping someone could take a look at the config and find what is faulty.

Answer 1

It seems that RewriteRule . index.php [L] is the culprit. It processes load.php, which loads all CSS and JavaScript, breaking it.
You can press F12 in Firefox, choose "Network" tab and follow one of the load.php links in the list of loaded files. See what happens. Most probably, it gets redirected into wiki pages.
