RewriteEngine On
#In some cases where you have other mod_rewrite rules, you may need to comment out the following line
#and change it to match your folder name. This resets the other mod_rewrite rules for just this directory
#If your site was www.example.com/forum, the setting would be /forum/
RewriteBase /Forum
# Send css calls directly to the correct file VBV-7807
RewriteRule ^css.php$ core/css.php [NC,L]
# Redirect old install path to core.
RewriteRule ^install/ core/install/ [NC,L]
# Main Redirect
RewriteCond %{REQUEST_URI} !\.(gif|jpg|jpeg|png|css)$
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?routestring=$1 [L,QSA]
# Because admincp is an actual directory.
RewriteRule ^(admincp/)$ index.php?routestring=$1 [L,QSA]
