Good afternoon. I'm having problem in module psa-firewall in Plesk 9.5.1 with CentOS 5.4. When I try to install the module, gives the following error: N) Install packages; S) show the list of packages, L) Return to list primary components; Q) Cancel installing; Select an action [N]: File downloading PSA_9.5.1/dist-rpm-CentOS-5-i386/opt/modules/firewall/psa-firewall-1.0.1-cos5.build95100410.11.i586.rpm: was skipped because of md5 checksum match. Starting installation of packages Installing the package psa-firewall-1.0.1-cos5.build95100410.11.i586 Trying to start service mysqld ... done Trying to establish "test connection ... connected done ===> Setting up FILE owners ===> Installing database error:% post (psa-firewall-1.0.1-cos5.build95100410.11.i586) scriptlet failed, exit status 1 I need to disable the iptables service? And in the case of psa-spamassassin, I also must disable the spamassassin service and just let the psa-spamassassin running? Thanks.
