Images and css files not loading on live server

@jreklund great news I have now managed to get this problem resolved with the help of my hosting gurus!!
Apparently on Apache hosting when using the htaccess file needs to have the SetHandler line changed so that it only affects php files and not all files as was happening on my original htaccess setup!!

Here is the modified first lines for the htaccess file:

<FilesMatch "\.(php4|php5|php3|php2|php|phtml)$">
SetHandler application/x-httpd-ea-php73-lsphp
</FilesMatch>

I hope this benefits anyone else in a similar situation.

Thanks again for everyone who has replied to this thread I do appreciate all of your help with this.
