Can’t pay (500 Internal Server Error wp-admin/admin-ajax.php

Hi guys!

Hope you are well

We try setup your plugin WP Gift Voucher on our site https://elfzhou.divertdigital.com/gift-voucher/
We had an error at the last step of the payment (we use stripe) 500 Internal Server Error wp-admin/admin-ajax.php

We tried to use both real and test stripe keys, but this does not solve the problem.?
This problem may be due to the fact that we are using the free version of the plugin, although you did not say this anywhere in the description and the payment should work?

This is our old project, so we have the following versions:
WooCommerce Version: 2.6.2
WordPress Version: 4.5.3
WooCommerce Stripe Gateway: 3.0.2
PHP Version on Server: 5.6.30

We can see from your description that your plugin supports these versions, as it is important for us to stay at these points. Otherwise, we will have more problems with other plugins when updating.

If to solve this issue, be sure to buy the pro, let us know and we will buy – it is not the problem for us.

We will be grateful for a quick response since we need to have time to launch this plugin before the holidays so that our client can use it

Many Thanks!
