Admin Panel not displaying on front end

Hi there,
The admin panel isn’t displaying on the front end of my website. I’ve tried all of the following to no avail:

1. I’ve checked the box to display the admin toolbar in my theme settings.
2. I’ve checked the “show toolbar when viewing site” box under User Profile
3. I’ve deactivated all plugins
4. I’ve tried one of the default themes and the admin panel is still absent.
5. I have <?php wp_footer(); ?> at the end of footer.php right before </body>
</html>
6. I’ve tried logging out and logging in again
7. I have <?php wp_head(); ?>
</head> in header.php
8. I’ve put a name in my profile name box.
9. DEBUG came back with the following (although I must confess this means nothing to me:)

Not sure if it’s related, but the preview button in my Divi Elegant Theme takes me to a page that tells me I don’t have permission to preview a published page when logged in. Elegant Themes tell me the admin panel issue has nothing to do with them – which makes sense, seeing as the issue remains with native themes.

Really hope you can help.
Many thanks in advance
