ok ive tried installing this on a v1.3.6 templated site and a stock v1.3.7 site and I just cannot get it to work.

If anyone is willing to help me out I can give you $100USD upon a successful install.

It seems to always install but when I go to admin to activate it it has the error

Fatal error: Class coreadvancedsearchresultseourlplugin: Cannot inherit from undefined class coreadvancedsearchseourlplugin in /home/xxx/public_html/includes/classes/seo/seo.url_plugins/__core__/advanced_search_result.php on line 14

this error is similar on both v1.3.6 and the v1.3.7 install using the 3.0 beta 1 they are both on seperate servers so I must be doing something wrong
