I am having troubles getting my new e-commerce site working with my .htaccess file.
My developer has this version of the file running on all other e-commerce sites with no issues, but here with my LunarPages(LP) hosting account it is not re-writing the urls.

I have confirmed with LP support that Apache is on and the mod re-write is on as well, which are the 2 requirements of the htaccess updates. If anyone can recommend how I can change this to work correctly to generate search engine friendly urls that would be much appreciated.

Thanks.
If you would like the link to my site, please let me know and I can give specifically to you to view. The cart software is similar to xcart, litecommerce,zen cart cscart and such as far as the end results, where the pages are always mysite.com/index.php?target=information-to-follow-here, and I want to convert it to: mysite.com/sef-url.html

Here are the contents of the .htaccess file I am using/was given:
DirectoryIndex index.html index.php

<IfModule mod_rewrite.c>
RewriteEngine on

RewriteBase /
RewriteRule ^([^/]*/)?[^/]+p[-_]?([0-9]+)\.html$ $1index.php?target=products&product_id=$2   [L]
