Try to deactivate all other plugins except the AST and WooCommerce and check again. * Thanks * Thread Starter [webtranquility](https://wordpress.org/support/users/webtranquility/) * (@webtranquility) * [3 years, 7 months ago](https://wordpress.org/support/topic/critical-uncaught-error-41/#post-16353231) * Ok, I will try that and revert, thanks.

processing checkout. Please try again.”, I get to see the order as “processing” in my dashboard. I have activated the Plugin back. If you will be able to test for me to be able to pinpoint exactly what the error is, I will be very grateful.Thank you.
