Cannot redeclare PEAR Error

[jNk]

Dont see any info related to this problem in the apache error log.
The RC 2.1 pear.php in the RC 3.1 generates error message too, refering to the same : Cannot redeclare _pear_call_destructors()

Well I have run out of ideas that's one very odd error that your getting, and I have hit my limit of odd error PEAR knowledge. Try asking the RoundCube mailing list and/or posting on Server Fault there is a lot of smart people who may have run into this error at some point.

Thanks for your effort and I hope somewhere somebody has got unlimited limit of odd errors knowledge

I will post the solution here when I've got it.

I have this error in the roundcube log too.

PHP Fatal error:  Cannot redeclare _pear_call_destructors() in /httpd/mail/program/lib/PEAR.php on line 771

I also noticed the other problem, when i first login (count of httpd start),roundcube just show me the blank page, after this i can login every time.
