When trying a payment using PayPal, I get the message "The seller accepts encrypted website payments only"
This means that you have enabled the encrypted website payments buttons option. You need to disable it again first - don't worry it is safe to do so as Bookeo uses PayPal's IPN technology to validate payments anyway.
1. Login to your PayPal account
2. Click on Profile
3. Click on My selling tools, then on Website preferences
3. Turn the Website Payment option OFF
