Alerts missing on 5.3

Just installed 5.3 - has anybody else got the problem? All my alerts and server monitoring stuff has disappeared!

I just finished upgrading to 5.3. No issues with my alerts…

My alerts are not visible either, but I can confirm that why you can’t see them, they are still working. Also the alerts database on the server appears to be intact. This looks to be a GUI issue.
I did report the bug.

OK thanks, I’m finding all sorts of other weirdnesses. I’ll post something about them
