I can't access account information

I've been trying to access my account for about a week now with no luck. I'm seeing a whole bunch of forum posts about a permission glitch when people were migrated from a legacy system, so I figured to give this a shot. I'm seeing "Sorry, This Isn’t Working Right Now" and similar messages trying to access anything but my mail. I ran thru all troubleshooting steps posted in other forums but got the same messages.

Thanks for any assistance.
