We have several forms on our site that work properly. However sometimes the customers get an ajax error message after they hit the submit button. That is very annoying because makes the system unreliable. What can cause this the ajax error?
I have the exact same problem after updating WP: AJAX ERROR. Website is using php 7.2, latest WP. I looked at the log file and did not see any error. Please explain how to fix it. Thanks!
