I was trying out the staging feature today for the first time. I clicked the wp-admin link from the hosting dashboard and got the id/password screen. I entered the id and password I found on the hosting dashboard. The first few times I tried this the login screen just popped back up again (userid was still there, but password was gone.). I started creating this support ticket and went back to get a screenshot and this time after entering the userid and password I got a screen .
"Error 404 - Not Found
This resource cannot be found.
Check the URL and try again, or go back where you came from."
Please see attached screenshots. I'll attached the screenshots on next reply as this screen doesn't have an attach option.
