I have some problems with adamin-ajax.php - Console showing something like this: console screen
I using few Wordpress plugins. The most important is: "WP Cost Estimation & Payment Forms Builder". Since yesturday I also using "WP Mail SMTP by WPForms" but I don't thing this plugin could make any problems with Ajax.
Suddenly Estimation form stoped passing - infinity loading page. Same on the backend in admin panel :(
The most interesting is that I did not makes any changes, only installed this SMTP plugin to solve mail problems.
Where can be a problem?
