I have a problem on one of the Polish servers (NetArt / Nazwa.pl) with the redirect.
In the htaccess file I have:
RewriteRule !.(js|ico|gif|jpg|png|css|mp4)$|(forum\/|pub\/) index.php [L]
For all other servers, it works without a problem here return 500 err. Please help me. After changing ! to (. +) gets a 404 error.
