Avada Fusion Builder and WordPress 5.1.1 Conflict

I believe something is wrong with WordPress 5.1.1 page editing rules.

Only Gutenberg works to edit sites.

When I use the classic editor t edit sites and click “update”, the site redirects to domain.com/wo-admin/post.php with a 404 Error. The same thing when I edit with Fusion Builder. Disabling Gutenberg (Disable Gutenberg or Classic Editor plugins) does not fix the issue.

Also, separately installing the Gutenberg standalone plugin completely disables both the classic editor and Fusion Builder.

Meanwhile, Fusion Builder contents are not portable. I can not edit with anything else.

Something is pretty not right and I have tried everything including fresh WP installs and some PHP edits. I need help, please.

And this is happening across all my different sites running different versions of Avada/Fusion Builder. The same experience across them all.
