After further testing whilst havin the htaccess file supplied with the SEO mod active on the site it knocks out the coupon module, when a customer enters a coupon code the site just redirects back to home.php
address also shows .../javascript%20document.couponform.submit();
instead of the usual .../cart.php
Changing the htaccess file for me just results in a non functional site at various stages.
ive posted the htaccess details in the hope someone might be able to modify it & keep the site working which is outta my realm.
Code:
DirectoryIndex home.php index.html index.php
RewriteEngine On
#RewriteBase /shop
# Don't rewrite requests for any files, directories, or symbolic
# links (shortcuts) that exist on the filesystem.
RewriteCond %{REQUEST_FILENAME} !-f
