Hi, I'm building a new client site on WordPress with Brizy and none of the mailing list management apps will connect through the web form. 

• The Error: POST admin-ajax.php?action=brizy_get_integration_account_api_key returns a 503 Service Unavailable (or 500).

• The Payload: The response has a Content-Length of 50, indicating the server is intercepting and aborting the request.

• The Environment: Web Server (GreenGeeks) with no ModSecurity, may be affected by LiteSpeed's internal request aborting.

• The Trigger: This began following the Version 2.8.4 update. Previous website email collectors using mailchimp were built successfully with Brizy.
