While I wish I had a solution to offer, I wanted to at least report that I am also experiencing the exact same problem… Tried to launch from a Staging Environment but all traces of the Staging beta is gone, except for the red “Staging Environment” button. Now, when I click it on, it takes me to an error page stating “Sorry, you are not allowed to access this page.”
I’m using a migration plug-in to migration the entire staging site to production.
I did locate the Staging Environment button is part of the MOJO Marketplace plug-in. When I deactivated the plug-in, the button went away. Searching through MOJO Marketplace support doesn’t seem to come up with any answers either though :-/
Hopefully someone figures out a way to fix this.
I’m in the same boat. Would love some assistance with this issue.
