The first 2 issues are just due to the 2 empty conditionals on the ‘Group Log In’ group (the 2 red squares in the image you included).

So just remove those conditions, or define them, depending on what you’re trying to do.

The second 2, I can’t be certain from the image, but it looks as though a workflow action is trying to set a custom state that doesn’t exist (it’s probably been deleted or copied from another element).

You can check what custom states the element has by clicking on the ‘i’ button in the top right of the element inspector. Or just see where the issue takes you when you click on it in the issue checker.

It will probably take you to a workflow action - you could just delete it as it’s not currently doing anything - but my guess is that at some point is was to do with setting the state to control whether the signup group is displaying a login or a sign up form, so with the missing states it wont currently work - so you’ll need to make sure they are there and working correctly.

It’s probably a good idea, if you haven’t done so already, to work through the basic Bubble tutorials so you can get a good understanding of the basics such as using conditionals and custom states.
