admin-ajax.php 400 error – does not allow me to save settings plugins

Greetings,

I had issues with several plugins when I wanted to save information (particularly in the plugins setup, once they are already installed) and the console shows me there is an admin-ajax.php error 400. Since it’s happening in several plugins, I wanted to know if there’s something affecting the configuration of those plugins because they have the same error in common.
At the theme level – code, how can I solve this error?

Plugins I tried but didn´t work well: WP Mail Logging by MailPoet, Mailchimp, Smush, etc.

Hello,

If you have problems with third-party plugins then you should refer to the plugin’s documentation or contact their support for help. It is not our theme’s support scope.

Kind Regards

It also happens with a Plugin that came with the theme that I deactivated and once I tried to activate and set things up, it didn’t work.

If it doesn’t work with all plugins on your website then it might be an issue with your WordPress or with your hosting server. But it is not a theme bug or error.
