[Xyzzy]

pfSense 2.1.3-RELEASE, squid3 3.1.20 pkg 2.0.7, squidguard-squid3 1.4_4 pkg v.1.9.5

FYI, I receive the following error on installation and removal of squidguard-squid3:

Warning: file_put_contents(/usr/pbi/squidguard-i386/etc/squidGuard/squidguard_conf.xml): failed to open stream: No such file or directory in /usr/local/pkg/squidguard.inc on line 1031

Relevant code in squidguard.inc:

1029   # store cfg cache
1030    $cfg_xml = dump_xml_config($sgxml, F_SQUIDGUARD);
1031    file_put_contents($sgxml[F_SGCONF_XML], $cfg_xml);
1032    conf_mount_ro();
