Prerequisites

• [ x] I have searched for similar issues in both open and closed tickets and cannot find a duplicate.

Description

I have been in contact with helpdesk and they couldn't resolve the issue and referred me here.
I'm having a 413 Error when saving a large page. The error occurs on that page when duplicating a section.

I have been in contact with my hosting provider and we have upped the PHP limits as directed by the helpdesk.

Steps to reproduce

On my page http://makemathmoments.com/academy
Duplicating any section will cause the error.

Isolating the problem

• [x ] This bug happens with only Elementor plugin active (and Elementor Pro).
• This bug happens with a default WordPress theme active.
• [ x] I can reproduce this bug consistently using the steps above.
