OK, this may be custom code so I understand if nobody can help.
On the site http://www.divorceforcedsale.com, if you are not registered as a "seller" using the membership+ plugin, you cannot post a classified.
Right now when you can click the button "Post a Classified" which links to the visitor protected page of http://divorceforcedsale.com/?page=ads
Since they cannot access that page, it take them to a generic login page. Can I redirect them to the http://divorceforcedsale.com/register/ which will allow them to join via the membership plugin?
The page itself it protected under URL /?page=ads
Strip query strings from URL - NO
Regular Expression - NO
