I am trying to: Add a relationship to a post in the WP admin editing screen for the post.
Link to a page where the issue can be seen: requires login. Easy to reproduce though. Add and activate the free GiveWP plugin to a site running types 3.0 then try to add a relationship to a post from WP Admin while editing one of the posts in the relationship.
I expected to see: The ability to save the relationship once I chose the other post (two Toolset Custom Post Types but not sure that matters).
Instead, I got: Could not press the save button.
When I disable Give, I am able to save the relationship.
I just re-tested this to see if the problem still occurs with the current plugins and it does not. I'm not sure whether the fix happened with us or with GiveWP, but the post relationship section on the post edit screen is now fully functional, the save button works (maybe a minor styling issue with the button).
