Login problem Squirrelmail

I didn't understand why I cannot login when the message says:

Code:

Error opening ../config/default_pref
Could not create initial preference file!
/var/lib/squirrelmail/data/ should be writable by user www-data
Please contact your system administrator and report this error.

I check on configtest.php, but I got the error page, grrrr
What have I found from old thread here at howtoforge http://www.howtoforge.com/forums/showthread.php?t=32739, yes it tells
chmod -R 777 /var/lib/squirrelmail/data but it doesnt works for me. Why? I has check which owner by /squirrelmail/data and its www-data.

Here are the error log:

Do have you better idea how to solve this dumb error? Thank!

 

Yes, it work.

EDIT: Could suEXEC a privilege issues?

 

Okay. I have Boonex Dolphin and it needs suEXEC to be enable because phot, video and etc could upload if suEXEC is enable. Do there is a solution of squirrelmail to get working while suEXEC enable e.g SSL or wildcard?
