Help!! Trying to use Elementor but I’m getting a 404 server error when I click

I’m trying to use the Elementor plug-in but no matter what I do, it takes me to a page not found.

I’ve tried with the default theme on WP, and also with another plug-in called Starter Templates but I keep getting this error. “Edit Site” is also not working. I’ve gone back to restore a blank WP site and start over but no matter what I do, it either stays on the loading page forever or gives me the “not found” page. For context, I am using GoDaddy, on a Web Hosting Economy Plan.

What am I doing wrong? Any help at all would be greatly appreciated.
