Welcome module profile link does not work?

Trying to use the ED Welcome module for login and quick links. This the standard module.

After logging in:

1. clicking on the username seems to generate the right URL, but there is no data.
2. clicking on the Edit Profile presents a second login screen? Logging in doesn't seem to work.
3. All the other links do not show any data.

I don't know if this module is incompatible with our recent customizations, but that seems unlikely. Appreciate your help.

Thanks!
