The same for me.
I think it was working before I did the Update to PHP 5.3.3 (via plesk Update)
but I can't say, if that really is the "problem".
---------------------------------------------------------------
PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE
Plesk Panel 10.4.4 MU#20
CentOS 5
Linux 2.6.18-194.26.1.el5xen
PHP 5.3.3-1.el5_6.1 (updated with plesk update)
MySQL 5.0.77-4.el5_6.6 (updated with plesk update)
Apache 2.2.3-53.el5.centos.3
PROBLEM DESCRIPTION AND STEPS TO REPRODUCE
The "Files"-tab in the advanced power-view does not work.
So no private or public files can be uploaded via the panel.
ACTUAL RESULT
Error "Internal Error: OK"
and a Message "Folderlist can't be created - retry"
EXPECTED RESULT
List the folders and do not display errors
