I have it set to allow members to buy the highlighting, bold and italics. I can select them for purchase and then get forwarded to a page that states "Please click on the link below to process your PayPal payment". Once I click it I am suddenly redirected to the "showmembers.php" page. It didn't allow me to finish the ad purchase.
I have the base price set for the ad as 0.00. They only have to pay for enhancements if they want them.
I have my paypal info added under Payment Options and enabled paypal.
I have it set to allow every usergroup the ability to use the enhancements and I have it set to require payments.
I must be missing something somewhere.
