I can't do anything on my wesite

And your .htaccess in the public_html folder has the following in it?;

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{HTTP_HOST} ^www\.(.*) [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [L,R=301]
RewriteCond %{REQUEST_URI} !\.(js|css|gif|jpg|png|ico)$ [NC]
RewriteRule ^(.*)$ index.php [QSA,L]
RewriteRule ^get/([0-9]+).gif$ /click/siggy/$1 [L]

Would you be against me looking at your files on your host? Or would you not be comfortable with that?
