Error during purchasing membership pack
hi, i have a problem related to the purchasing of the membership pack in my website. I'm using wordpress 3.2.1 and ClassiPress version 3.1.2.
I setup classipress "Charge for Listing Ads" to yes and enabled Membership Packs, the Price Model is seto to fixed price per ad.
When a client try to buy a membership pack gets this error: "Your session or order has expired or we cannot find your order in our systems. Please start over to create a valid membership order".
Could you tell me please what's the problem?
