[solution] unable to get on line/webgui

[Bulldogg]

if you have a old version of squid on your box you may want to manually remove it

[2.3-RELEASE][root@pfSense.localdomain]/root: cd /var/squid
[2.3-RELEASE][root@pfSense.localdomain]/var/squid: rm -rf *

use at own risk it worked for me

amd64
10.3-RELEASE
FreeBSD 10.3-RELEASE #4 05adf0a(RELENG_2_3_0): Mon Apr 11 19:09:19 CDT 2016     root@factory23-amd64-builder:/builder/factory-230/tmp/obj/builder/factory-230/tmp/FreeBSD-src/sys/pfSense
