When I browse the cards this error message appears

[abdo.nh]

This is a known compatibility issue with the Sidebar Table add-on:

Add ons and trouble syncing

This appears to be a compatibility issue with the Sidebar table add-on. I’ll log the issue so we can look into it later, but for now you have several options: Delete/Disable the Sidebar Table add-on. If your browser’s layout appears messed up after doing that, please go to Tools > Preferences and click the Reset Window Sizes button. If you don’t use AnkiHub’s Smart Search feature, you can toggle it off from AnkiHub > Config > Feature Preferences > AnkiHub Smart Search.
