I am at the "Updating database to version: 7.2.2 If at any time this step times out you may just refresh this screen and it will continue" step of upgrading to 7.2.2 with nothing further happening for about 30 minutes.

It still seems to be doing something, but this is all that I see on my browser.

Does anybody know how long I need to wait for what I understand is the final step? Should I hit "Refresh/Reload"?

I would appreciate some assistance.
