I get the "System error 13: Permission denied" error in Plesk CP during some operation.

APPLIES TO: Parallels Plesk Panel for Linux/Unix




Most probably Plesk Admin Apache cannot access some file because of lost 'SUID' bit on the wrapper.


Make sure that the following files have proper permissions:

# ls -al $PRODUCT_ROOT_D/admin/sbin/*wrapper
---s--x--- 1 root psaadm 13120 Jun 13 21:51 ./admin/sbin/mod_wrapper
---s--x--- 1 root psaadm 13632 Jun 13 21:51 ./admin/sbin/wrapper

If you see different permissions, use the "chmod 4110" command to correct them.
