When I try to view my web site files, it sends me to https://www.homestead.com/~site/jws/launchSBPlus.action where I get an error message.  It has been sitting for about 15 minutes now, unchanged. 

In addition, I am trying to upload photos of my error messages but I keep getting error messages for that too.
