Is this a…:
Performance issue Steps to reproduce this issue:
Step 1: Create a residential address and submit and PUR, do not enter any field Coutry, City, Street.
Step 2: Try to approve this PUR in WME as an editor, the WME will prompt a bug notification: “Invalid house number format” and WME is freeze with 1 edit unsaved
Now I see you problem. So, first of all, this error is expected, cause ‘house number’ is mandatory field for the residential place. Another thing that the ‘Save’ button is greyed out and WME is stuck after you close the error. I cannot repro it in Crome and Safari, I tried with you link as well (sorry, I approved second PUR while checking (the one with photo); the ‘New Place’ PUR is still there) and couldn’t repro it either. Can you please check in Crome just to make sure that it’s browser specific issue? And also may I ask you to repro this issue with the Console (Developer Tools → Console) opened?
