Meta Box

Have you tried the new login credentials I provided yesterday?

I don't understand what the problem is. It's right. I just logged in using different browsers (in incognito mode), and it works. I've now reset the password because the video you posted displays my credentials to anyone who cares to see it...

I'm setting up a new user and will resubmit those credentials via the contact form.

I submitted it again.

Were you able to find anything?

No, I do not use a custom field with the type 'taxonomy' or 'taxonomy advanced.' I have deactivated all plugins except for Meta Box and Meta Box AIO, and the issue persists. For what it's worth, I have other CPTs and taxonomies set up, and they work fine. I'm using Oxygen, so switching themes won't help, correct?
