Running 2.2.0.0
Downloaded friendly seo for my account page, newsletter and all that lot. installed it and done all the changes, now the page is coming up with 'The page you have requested can not be found' Tried contacting the dev and no response

So I've done some digging, I've changed .htaccess , enabled SEO Url links in admin, and i checked phpadmin and everything looks correct.
The only thing i cant find is seo_url.php in catalog/controller/common. Am i suppose to have this file?
