Hi,
I'm using webhost4life as an ISP. They migrated my site to a new box and requested that I change my database connection string in my webconfig.
After I did that my main portal is fine, but one of my child portals is not showing any modules and I get a A critical error has occurred Object reference not set to an instance of an object.

Has anyone come across this before?  Any advice is appreciated. Thanks

The event viewer gives me this error message explanation:
