Cannot drop database


Mybe you don't have rights to do that. Google for GRANT ALL....

Mybe you don't have rights to do that. Google for GRANT ALL....

the traffic 2 DB is my working DB. my website and mobi site connect to this db. i log in every day with: mysql -u traffic2 -p traffic2 and i use the same password everyday. when i set this up many moons ago i did:

mysql -u root -p
> CREATE DATABASE traffic2 CHARACTER SET 'utf8' COLLATE 'utf8_general_ci';
> CREATE USER traffic2;
> GRANT ALL ON traffic2.* TO 'traffic2'@'localhost' IDENTIFIED BY 'password';

anything im missing?
thanks

finally got it to work :) thanks all
