Hi all
I have TSL 2.2 with squirrelmail 1.4.9a installed (from tgz). When upgrade php from 5.2.0 to 5.2.1 , squirrelmail has broken with multiples errors for example:

SAFE MODE Restriction in effect.  The script whose uid is 500 is not allowed to access  owned by uid 0
in /home/httpd/html/squirrelmail-1.4.9a/functions/global.php on line 405

When restore php 5.2.0 all function OK..

Is incompatible squirrelmail with newer php ?

Regards,
PD: Sorry for my poor english
