A couple of things

- #3 and #4 are the same, have you forgot something else?

- you need a new section on the web.config for this to work

-  the <cuteChat  tag is malformed. Al least the /> is missing.

- Should the connectionsTring be blank?

- If I'm not wrong this (CuteChat.DNNLib.DNNSqlDataProvider,CuteChat.DNNLib) specifies a type and an assembly. Are you sure this are the names? DNNLib is not on my installation.

 

If I leave this as you pointed I get:
