ehcp installation mysql password howto
while you install ehcp, you need to enter your mysql root password.
if you dont know it, you may recover it as described here: http://www.ehcp.net/?q=node/160
if you are not able to learn or recover, i advice you to do a clean ubuntu install.
Please note that, if you reset your mysql pass, and if you have other software on your server that uses same mysql root pass, then they may not function after recovery..
But if you just installed your server, you may reset/recover your mysql pass safely...
if you need further help, look at troubleshooter at your ehcp installation, or http://www.ehcp.net/helper/yardim/cats.php
if you get this error, after a while, after you used sometime your ehcp:
either reset your ehcp pass as in your config.php in ehcp dir,
or change config.php to reflect your new ehcp mysql user pass.
you may also have deleted ehcp mysql user accidentally, then add that user in your phpmyadmin.
