ESXi 6.5 – Memory limit doesn’t accept the negative value -1048576

Memory limit doesn’t accept the negative value -1048576 error

MacOS Sierra 10.12 and Safari 10.0. Reopening the ‘edit’ screen produces a Memory limit doesn’t accept the negative value -1048576 error. This was also in the previous OS X and Safari error. Reloading the page (cmd + R) fixes it, then you can reopen the edit screen and make changes.

I use Firefox instead, it´s easier.
