Urgent help needed

[sunnyjey]

Since last couple of days, Ajax has stopped working on our J site.

The cascade plugin, databasejoin plugin and even in backend validation are not loading. The console shows following error:

Fabrik pluginmanager addTop ajax failed :  [object XMLHttpRequest]

Failed to load resource: the server responded with a status of 403 ()

I really dont know whats going wrong. Even dont know whether this is related CORS, htaccess, fabrik or joomla.

Any pointer would be highly appreciated.

Joomla & Fabrik 3.x version latest. Php 7.4

What has changed in these days?
Server settings (error 403 = forbidden)?
Really still php7.4?
Something like Admintools?
Enable J! System debug and Fabrik debug. Maybe you'll get some more infos.

Thank you Troster for prompt reply.

I am still hunting the source of error. Enabled debug but no help.

I am also getting 404 error in console for ajax request of fabrik at multiple places (database / CDD / group select / validation load). Not sure whether this is related to apache server, htaccess or mod_security.
