Unable to edit pages or posts from top Admin toolbar after changing to new theme

Hello!

Due to some (suspected) conflict between my theme and ip-geo-block, I cannot edit posts and pages on my site from the top WordPress Admin Toolbar.

Here’s what happens:
1) I view a post or page outside of /wp-admin/.
2) I go to the top WordPress Admin Toolbar and click the “Edit” link
3) It takes me to the URL /post.php?post={postID here}&action=edit, which gives me the error I set for when something is blocked by ip-geo-block.

However, I can still access posts/pages within /wp-admin/ (as well as the rest of /wp-admin/) absolutely fine. I suspect the issue is because that the ip-geo-block authorization URL variable/token somehow isn’t automatically being passed through to the “Edit” link in my toolbar.

For comparison, I can successfully access post/page editing if my URL looks like this: /post.php?post={postID here}&action=edit&ip-geo-block-auth-nonce={IP geo block token here} — and this is the case for navigating to post/page editing within /wp-admin/.

I suspect that there’s something wrong with the theme I just installed that’s preventing the token/corresponding URL variable from appearing in the Admin Toolbar. I say this because I’ve already gone through a process of elimination where changing to different themes means this issue no longer occurs.

Does anyone know what might be up with my theme/what area of the code I should focus on in order to get the token/URL variable to show up again? Thanks in advance!
