When logged into sunstone as oneadmin the VM’s menu is missing that should be above the templates menu. The only way to interact with VM’s is via the command line.
The sunstone error message shown is: Action VM.list not defined
We cannot reproduce this in our 4.12 platforms. Could you reload to flush
the cache so we get rid of any js from previous versions (you may want to
try from an incognito window also)?
If the problem persists are you getting any error from the console of your
browser (e.g. Developer tools Ctl+Shitf+i in chrome…)?
