Every once in awhile you get bit by the Law of Unintended Consequences. What is this law you ask? To quote wikipedia:
The Law of Unintended Consequences states that any action will produce some unintended consequences…
This maxim is not a scientific law; it is more in line with Murphy’s law as a warning against the belief that we can control the world around us. In other words, each cause has more than one effect, which will invariably include at least one side effect. The side effect can potentially be more significant than any of the intended effects.
Our blog got hit with that big time since late last week when I installed and turned on the WP-SuperCache plugin. I thought I’d been installing a performance improvement, but I ended up breaking the comment system due to a bad interaction with Spam Karma 2 (SK2). Most people who’ve been trying to leave a comment in the past few days have been shunted to the moderation queue or blocked as spam.
After some web searching I found two sets of directions to fix this. The first is a plugin from Priv for SK2 that makes SK2 notify WP-SuperCache when its updates things. The second was some code modifications from quenting I needed to make to both SK2 and WP-SC to make some ‘magic’ anti-spam stuff that SK does work.
The end result is comments work again and should not have the false positives. Of course, I have to wait and watch the next few days to see if it actually is working… So comment away!
