When I try to delete or edit a node in my realtime database, I always get the info that I have to select a key with lesser elements to change something, else it is in read-o
Update 5/24/17: Problem resolved. Works now.
It seems the ability to click on a child node and promote it to be the top element of the tree is broken. Doesn't work for me either, even on a small database that is not in Read-only & non-realtime mode. I'm almost sure it was working a day or two ago.
I'm seeing the failure when using Chrome. Just tried Internet Explorer. Its works there.
You're mixing three things here:
Your database console switched to read-only mode, which happens when you have a certain amount of data under it.
The warning is badly translated. Please file a bug report for that.
The database console doesn't handle clicks correctly anymore. I already reported that internally last week, and added your report to it. This bug has been fixed internally and will go into production by May 23.
