yiic stop to work on dev version

Hi folks,

I recently started a new project, however i normally use the dev version (trunk) to get the most recently version of framework, but now in this version (v1.1.9-dev) after created a new app using webapp command when I tried to use any yiic command nothing happened.

I try to run migrate command and yiic shell but the prompt just returns without any error or any message.

have you ever had this problem too?

How can’I debug this problem?

Thanks advance.

Is there anything in PHP log? Check it please.
