If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
You will not be able to test this from within the sitebuilder, however, if you press the 'preview' button and test the PayPal button from preview mode, you should see the PayPal button working properly.
Please give it a try and let us know how it goes for you. Thanks!
