403 Server Error when adding Javascript to page using HTML Widget in Elementor

Question

Using the HTML widget in Elementor Pro, I add a javascript tag to the page, hit update, and get a 403 error.

The javascript is a dynamic, simple sign up form that embeds properly.

I do not have any security plugins like WordFence that would be conflicting, and I have disabled all plugins just in case.

I have seen this: Update button does not work but I don't have access to the site's files, so I can't increase the memory limit.

Answer 1

Please follow these steps in order to whitelist the Elementor plugin:

1. Go to Wordfence -> All Options
2. Scroll down until you see Whitelisted URLs
3. Put /wp-admin/admin-ajax.php for the URL
4. Select Param Type: POST Body for the dropdown
5. Put actions for the Param Name
6. Click Add
7. Click Save Changes in the top right corner
