Awesome solution, this worked for me too!
Or it could be you’re accessing wordpress.org over HTTPS protocol. Their CSS files are served up over HTTP, so there’s some cross-domain issues preventing CSS load. I had HTTPS everywhere plugin enabled for Firefox, and had the same problem. I turned off HTTPS everywhere for wordpress.org to fix the problem. See this: https://trac.torproject.org/projects/tor/ticket/4209
FYI – I have had the same problem pop up recently, and I tracked it down to this custom search filter function in functions.php:
function SearchFilter($query) {
if ($query->is_search) {
$query->set('cat','3');
}
return $query;
}
add_filter('pre_get_posts','SearchFilter',10);
