IPCop - Copplus Log Date Fix

At our school, we use IPCop (version 1.4.21) as a gateway. In addition, we utilize the Copplus (Cop+ version 3.0.2) add-on for content filtering. I ran into a problem with the change from 2010 to 2011 date. The log analyzer did not have an option to select 2011, so I had to find a solution.

I looked into the /home/httpd/cgi-bin/dansguardian/log.cgi file and found a couple entries that did the job.

You can see that in my cgi file, it is around line 614.
I edited it using WinSCP. I changed the 2010 value to 2011, and it worked!
