admin-ajax.php error with 500 code on checkout page

Hello @zayedibn

Thank you for choosing CartFlows and writing in!

Receiving a 500 server error means that there is some critical error on the server while processing the current ajax request.

This type of error message gets logged in the WordPress log file. So, can you please check what is the exact error message is logged in that file?

You can follow the below steps to read the log file.
– Navigate to WooCommerce -> Status -> Logs Tab.
– Select the file whose name should be started with Fatal error followed by the date on which the error has occurred.
– Share the error message here in this message so that I can get an exact reason for that error.

I hope this helps.

Looking forward to hearing from you.
