Help with links back to correct site.
I have two sites; TiresOverstock.com and Tires.TiresOverstock.com
I bought the authorize.net plugin for Classipress. Tires.TiresOverstock.com is working perfectly. When a customer pays for a membership, it then links back to the Tires.TiresOverstock.com homepage. It is a restricted site for dealer, distributors and manufacturers in the tire industry.
TiresOverstock.com is the public site and when payment is made, it should link back to TiresOverstock.com's homepage, but it links back to the Tires.TiresOverstock.com homepage and this shouldn't happen because Tires.TiresOverstock.com is the restricted site.
The one that is working is set to have authorize.net host the site. How should I setup TiresOverstock.com so that it links back to the correct site. I've spoken to authorize.net several times, but they don't seem to be able to find the solution.
