Going to CB>Tabs>Last View, I dont have a Parameters tab on the Last Views Tab
I have the latest release versions of CB 2.0.7 and Last Views Plugin 3.0.2
Still not to worry, I run a small piece of perl every hour to delete the moderators out of the table and also compact the guest view, as in 1 row per profile viewed by guests rather than 1 row per guest.
I have no interest in storing IP's for guest views and prefer to keep the db running as efficiently as possible (says an Oracle DBA of 20 years experience)
If anyone is interested in the code, you will nee to replace the #_ with the prefix to your table names on multiple lines.
On line 15, you will need to update the group id's with the groups not to log OR remove 15,16 and 17 if you just want to compact the guests.
Line 64 needs updating for credentials, if possible use the method of storing the password in a separate secure file (filename starting with a . and has permissions 600)
You will need to be able to run perl on your host and a method to cron.
