wix paid memberships

Hi, I grabbed the paid membership option from the wix store. Set it up but of course i wanted to try it out so I put the price to £0 to gain access as I do not know how to approve for free. (if you know how that would be great to know) Upon trying to complete payment it will not accept card details or direct to paypal. It displays the message “try again” Is this happening to any of you?

Another thing is it possible to change the default message that appears when you do not have access to the area?

Hi Craig,
since it is not directly related to Wix Code, could you please contact the support directly via email support@wix.com ?
