phpMyAdmin - Error

[mingswanfoo]

I was able to login to view "phpMyAdmin" this afternoon, now I try again but this message appear... I don't have a clue what it says:

phpMyAdmin - Error
Cannot start session without errors, please check errors given in your PHP and/or webserver log file and configure your PHP installation properly.

Anyone know what's wrong? I tried to re-login my cPanel but there is no changes. I didn't do any amendments in there..

Help needed...
