      I tried running the script below on a server running 2.2.2 (without the pfBlocker package as it is not available for 2.2.x) where the config had been restored from a server with 2.1.5 and the pfBlocker package on and it didn't work: the config still had the pfBlocker config in…  Output at the bottom of this post:

      @BBcan177:

      Here is a script to remove the previous pfBlocker package from the pfSense config.xml

      So please make a full backup before proceeding. Please post back if you were successful in removing the old remnants of this package…

      Save this script to  /usr/local/www/removepfb.php

      then from your pfSense GUI

      https://x.x.x.x:yyy/removepfb.php

      (Change x.x.x.x to your pfsense box IP  and yyy to the port setting used.)

      It will report to the screen with its activity.

Removed pfblocker
Removed pfblockerlists
Removed pfblockertopspammers
Removed pfBlocker Menu Entry

Fatal error: Call to undefined function getUserEntry() in /etc/inc/config.lib.inc on line 501

      Should I just remove the config manually using the nested grep example BBcan177 gave?

      grep "pfblocker" /conf/config.xml | grep -v "pfblockerng"

        P.S. The script removed nothing as far as I could tell: the pfBlocker rules were still present and the menu entry was still present.

          It won't remove the rules but it should remove the menu entry. Is this a full install version of pfSense. Might need to put the system into RW mode to save the changes if it's a nano/flash type version.

            greping the config file still shows 'pfblockersync'.  Should that be there?

              Thanks for pointing that out. I can't edit my original post, but please edit the script to include "pfblockersync" as follows:

                  Just tried running this - after copying the script to my pfsense VM.

                  I ran the script from Chrome and it just outputs 'Removing pfBlocker from the pfSense Configuration file'

                  Where exactly am I executing the script from?

                  Thanks

                      To install or re-install pfBlockerNG 2.1.1_2
                      https://forum.pfsense.org/index.php?topic=102470.msg647719#msg647719

                      Then you can install or re-install the pfBlockerNG 2.1.1_2.
                      The install should update the MaxMind (this take 5+ minutes) and proceed to completion.

                      Then you can remove the package

                        Many thanks for the new fix.

                        I have attempted a new install after modifying config.inc.  However the pfBlockerng entry under my firewall menu is not visible.

// Set memory limit to 512M on amd64.
if ($ARCH == "amd64") {
	ini_set("memory_limit", "512M");
} else {
	ini_set("memory_limit", "256M");
}

                          You are using the AMD64 version, try to increase to 768M:

                          
if ($ARCH == "amd64") {
	ini_set("memory_limit", "768M");
} else {
	ini_set("memory_limit", "256M");
}

                          Or wait until BBCan releases the fix

                            To increase memory_limit over 512M you also need to fix /usr/local/etc/php.ini, /etc/rc.php_ini_setup
