Hi @cronogargaros ,
I find it odd that the customer was able to submit a second time, as if a payment fails, a Pending Payment order is created and the cart is cleared. To pay, the customer would need to go back to that order via the My Account page or the link in the email they’re sent to complete payment.
This may be a caching issue. Do you have any caching plugins or server-side caching running on your site? If so, make sure you exclude the following pages from the cache through their respective settings panels:
* Cart
* My Account
* Checkout
There are more details about configuring caching plugins here.
If you don’t have any caching, the problem may be caused by either a conflict with your theme or with another plugin.
?
The best way to determine this is to:
- Temporarily switch your theme to Storefront
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
I hope this helps!
