Cannot switch between two created shipping methods
I am using x-payment 3.02, x-cart 4.77, light-responsive skin and x-cart's one-page checkout. I am using iframe for x-payments, so that the credit card is entered on the checkout page.
I have created two custom (added) shipping methods: Free Ground Shipping ($0.00) and Pick up ($0.00). (see attached)
When a user attempts to switch between the two shipping methods we created, x-payments hangs when trying to load the iframe. The solution is to refresh the page, and then the credit card iframe appears. (see attached)
This problem does not occur if we choose a payment method that does not invoke x-payments (eg. phone ordering), which makes me believe that the issue is with x-payments.
The problem also does not seem to occur if switching between a predefined shipping method (eg. UPS overnight) and a custom method. It seems to be confined to switching between two custom methods.
I cannot find any errors in the log files.
I hope you can help resolve the problem.
X-Cart version 4.7.11
