Was there some kind of update or something? Yesterday I worked on my app, run mode was working fine and I saved where I was and went to bed and this morning my save is good (no errors have popped up, everything looks as I expected) but run mode now loads a grey screen?
I have been having issues with test mode for awhile (it says there is an unexpected null in my login page - but I can't find anything) so I have only been using run mode for awhile - this plus some update is the only reason I can think of for it to randomly stop working overnight.
Any advice on how to fix this so I can test things again?
