I recently installed zen-cart on a new url and then added Ultimate SEO urls mod. http://imagenationclothing.com/

The mod seemed to be working correctly and changing the urls to seo urls when I clicked on the category pages, however now I can't log into my admin panel. Also, I started getting the 404 error: http://www.imagenationclothing.com/p...kirts-c-1.html whenever I go so something other than the homepage. After looking around for support and answers, it seems like it could be a problem with the .htaccess file that was added as part of the mod.

The .htaccess code is as follows:

##### NOTE: Replace /shop/ with the relative web path of your catalog in the "Rewrite Base" line below:

Options +FollowSymLinks
RewriteEngine On
RewriteBase /imagenationclothing/

# From Ultimate SEO URLs
RewriteRule ^(.*)-p-(.*).html$ index\.php?main_page=product_info&products_id=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-c-(.*).html$ index\.php?main_page=index&cPath=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-m-([0-9]+).html$ index\.php?main_page=index&manufacturers_id=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-pi-([0-9]+).html$ index\.php?main_page=popup_image&pID=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-pr-([0-9]+).html$ index\.php?main_page=product_reviews&products_id=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-pri-([0-9]+).html$ index\.php?main_page=product_reviews_info&products_id=$2&%{QUERY_STRING} [L]
RewriteRule ^(.*)-ezp-([0-9]+).html$ index\.php?main_page=page&id=$2&%{QUERY_STRING} [L]

# All other pages
# Don't rewrite real files or directories
RewriteCond %{REQUEST_FILENAME} !-f [NC]
RewriteCond %{REQUEST_FILENAME} !-dT
RewriteRule ^(.*).html$ index\.php?main_page=$1&%{QUERY_STRING} [L]

Any help is greatly appreciated - I'm confused as to why it would break the admin panel when it was working before.
