Apologies for the number of forum posts recently, I have a project that I put on the back-burner for months and now I have to resume..
There appears to be an issue with the Edit button plugin not appending the item-id to the URL. There is another post relating to this.
I have followed the documentation but if I leave to the Item-id evaluation rules nothing gets appended, If I leave to same item-id nothing also gets appended both resulting in a white screen.
I have temporarily got around this be hard coding the item-id in the plugin URL (see attached) however that results in the plugin being directed to a new form not to re-edit the form I clicked.
