Enable logging does not seem to work with mysql

[hjtoi-bugzilla@…]

I just did my first Trac installation at Dreamhost using mysql database. I have installed TracAccountManager? 0.2.1dev-r3857 and TracSpamFilter? 0.2.1dev-r6990 plugins. After installing the spam filter I was required to issue trac-admin upgrade command.

I was looking at the Spam Filter: Configuration options, and tried to enable logging. However, when I hit Apply changes the page refreshes and the box becomes unchecked. I checked that Spam Filter: Monitoring was empty, logged out, logged in as normal registered user, and made a change to the main wiki page. I then logged in again as admin to see if there were changes in Spam Filtering: Monitoring, but there was nothing.
