i just installed the 2.1 Update.
I had to uninstall and reinstall Squid+Squidguard+Sarg by my self.
After "automatic reinstall" during upgrade of pfSense Squid Squidguard and Sarg didnt work.
So i deleted and installed everything again over the webGUI Packages menu.

Now Squid+Squidguard worked fine.

Then i configured Sarg to create logs from Squidguard!

Sarg then told me in the System Logs "SARG: Cannot open squidGuard config file: /usr/pbi/sarg-i386/etc/squidGuard/squidGuard.conf"

To solve this problem: create a shortcut to the destination "/usr/local/etc/squidGuard" in the folder "/usr/pbi/sarg-i386/etc" over SCP.

Now it works fine, without errors!
:)

Just wanted to post my fix for that issue.

And sorry for my bad english! :)
