I also have this issue with my paid copy. Did you solve the issue?
Problem with Cloudflare SSL and elementor and WordPress 5 communicating. I shut down Cloudflare SSL now I can access editing in Elementor in WordPress 5.
I changed Load method in elementor settings with classic editor enabled. I will now attempt to disable classic editor.
Not Good..missing photo links..reverting back to classic editor
I have shared the login, awaiting your reply.
