Seems kinda weird issue for me. To be exact was following lithium blog tutorial.

EDIT adding mongo db configuration from phpinfo()

mongo

Answer 1

Make sure you're running the latest Git master of Lithium. The last release version was 0.9.9, and the Mongo PECL extension has made 3 major BC-breaking changes since then. They're fixed in the core, they just haven't been rolled into a release yet. Also, a user name and password are NOT mandatory.

Answer 2

Assuming you have correct host, port and login info make sure you have the newest version on MongoDb extension.

I had similar problem. Li3 uses mongodb://{$login}{$host}/{$cfg['database']} which wasn't supported by the older versions.

Answer 3

maybe it's this ticket (solved it for me):

Answer 4

I had to downgrade my PECL extension to get it working.
