I\'m hoping the hivemind has some more suggestions on dealing with this error from Yii Framework. The exact error, specific to our setup is:
I was facing similar error with MySQL. In my case the problem was that I had made a mistake in granting the rights for the user. Running MySQL client I got a proper "command denied message", but from Yii perspective it looked like the tables did not exist at all.
The solution was to grant the rights properly:
grant all on yiiapp.* to 'yii'@'localhost' identified by 'yii';
