Jon's questions

I've set up mysql and phpmyadmin and chose not to set a password when installing hoping that once set up i could login with root and no password but i get the following error from phpmyadmin:

Login without a password is forbidden by configuration (see AllowNoPassword)

I have previously moved the phpmyadmin folder to /var/www/

I have tried changing the following line

$cfg['Servers'][$i]['AllowNoPassword'] = false;

to

$cfg['Servers'][$i]['AllowNoPassword'] = true;

but still had no success, so i am wondering is there a way i can change the root passwords for both so i can access phpmyadmin and create databases.

Whats the simplest way to edit and add files to “/var/www”?

I can't seem to move folders or create new folders in the /var/www folder. This is the first time i have tried using Ubuntu and i can't seem to find a reason why i'm not able to move folders, i only have one account so should have all the priviliges.
