Thread:Project:Support desk/Problem with Javascript

I had a perfectly working wiki until four days ago, when I started to get the following mime type problems:

Resource interpreted as Stylesheet but transferred with MIME type text/html: "http://drebbel.net/wiki/load.php?debug=false&lang=en&modules=ext.slideshow.…face%7Cmediawiki.ui.button%7Cskins.vector.styles&only=styles&skin=vector&*".

Main_Page:17 Resource interpreted as Stylesheet but transferred with MIME type text/html: "http://drebbel.net/wiki/load.php?debug=false&lang=en&modules=site&only=styles&skin=vector&*".

Main_Page:20 Resource interpreted as Script but transferred with MIME type text/html: "http://drebbel.net/wiki/load.php?debug=false&lang=en&modules=startup&only=scripts&skin=vector&*".

Main_Page:1 Refused to execute script from 'http://drebbel.net/wiki/load.php?debug=false&lang=en&modules=startup&only=scripts&skin=vector&*' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

My site is drebbel.net/wiki

I tried including

AddType text/css css AddType application/x-javascript js AddType application/json json

into .htaccess to no avail.

I'm using a payed hostserver.
