I loaded the .htaccess file to the root of the site. I made sure permissions were set to 755 on it. I made sure the friendly url's were accessible. And then I updated the "Activate URL rewriting" setting in the ACP_CAT_PHPBB_SEO tab. But still, the friendly links do not show up throughout ...

So I went through the installation steps. I loaded the mod to an existing installation. I uploaded the robots.txt and .htaccess files assigning proper rights. And I am able to access forums via the new friendly url's. But my forum still uses the old -http://....forum.com/viewforum.php?f=5 style link...
