Hi Sara,
Thanks for reaching out to us on this! I’ll help you out on this…
First of all let me say this is an issue I haven’t seen in the past so not sure about it! In order to get more information about it, Can you please follow the steps described in our Testing for conflicts guide? This way we can see if this is a problem in our plugin or a conflict with the theme or other installed plugins. And also, it would be great if you could share your system information with me so I can check if everything looks right on that end.
Do you see the same issue when navigating Posts or Pages or any other post type in the admin? Can you see in errors in the browser console (more on this here)?
Please let me know about it so I can help you out,
Best,
Nico
