I am getting odd behaviour when direct linking to products in whmcs using the links provided by the WHMCS Integration Plugin.
I am getting extra product units added to the shopping cart and sometimes totally different products.
If I use the links directly from WHMCS - http://subscription.pozlystore.com/whmcs/cart.php?a=add&pid=1 - every thing works out fine.
I really want this to work but it is causing a whole heap of frustration at the moment. Please help.
