The site appears almost as normal, but no data is propagated in the modules and the following error is splashed across the top of the screen. I do not see any error logs in the event viewer on the server or the local workstation that is accessing the website. 

"A critical error has occurred. An unexpected error has occurred"

It seems to me that a link is broken between the database and the web server, but I can't figure out what it is for the life of me. 

I am using the SQL sa account to access the DB from the web.config file. 

Any help or guidance would be greatly appreciated.
