Since 2.7.2d I am now swamped with my customers who are registering for free events telling me they are being taken to PayPal which is asking them to enter a payment value - tested it and that's exactly what's happening!
Tried changing my payment options in the backend - Default is now Pay Later - Doesn't make any difference....
Fixed, just updated the package to 2.7.2e addressing this issue. Re-tested free events, 100% discount codes, paid events, combo of paid/free in the cart, etc. All looks good
