Hi @MACLAINE, have you tested access to your dashboard from another network connection to see if you can duplicate that error?  I'd start with that.  If you get the same error regardless of the network, please give our live support teams a call so we can review your active plugins, themes, and other components to see what could be causing that 500 error.  Thanks!
