I only accept Paypal and the Booking Form says that I accept credit cards and paypal. How do I edit the booking form to remove the credit card verbage and icons?
Since you accept Paypal, you do accept credit cards - that's one of the functions that PayPal does, though we do recommend using a regular payment processor in addition to PayPal:
Hi, I will not be accepting credit cards directly from your site. If a guest chooses to fund their paypal payment with a credit card, that is their business and has nothing to do with the payment types I accept here.
How do I change the verbiage to remove mention of credit cards and remove the icons?
I think there's a misunderstanding here - by virtue of the fact that you have configured a PayPal account, you do accept credit cards. This cannot be changed, because it's offered by PayPal.
OwnerRez knows that you don't have a separate credit card payment processor, and that's fine - the guest will be passed through to PayPal to pay using their credit card, or to log in to their own PayPal account and pay using PayPal funds if they prefer. In either case, that is handled directly by PayPal.
There's no option to remove the mention of credit cards or their icons, because they are inherently accepted via PayPal.
