There is a admin page that gives me this error on the page itself when I try to access it: “Sorry, you are not allowed to access this page.”

In the console it logs: “Failed to load resource: the server responded with a status of 403 ()”

the page: site/wp-admin/options-general.php?page=menu_editor

I staged the site on localhost, this same error occurs there as well.

Here is what I tried so far:
-conflict test with plugins
-making sure the directories have the 755 and files have the 644 permissions
