How To Fix WP-Cache And Spam Karma 2 (SK2) Issues

February 1st, 2007 • Related • Filed Under

WP-Cache and Spam Karma 2 are two of the most popular WordPress plugins. If I had to estimate, I would say that at least 30% of WordPress users are using at least one, if not both of these plugins.

Recently there has been a problem with WP-Cache not flushing its cache when a new comment has been left. Priv has worked out the issue is because SK2 intercepts certain actions, so WP-Cache doesn’t know that it needs to clear its cache.

Luckily Priv has put together a fix. All you have to do is the following:

  1. Download this zip
  2. Extract and drop the php into the sk2_plugins directory
  3. Flush The WP-Cache2 cache. Note: The latest versions of WP-Cache needs to be installed first and the old cache deleted, before this patch will work.

I’m so glad I found this fix as I can now get my WP-Cache/APC caching combo going again so that I get the best of both types of caching. I’d previously turned WP-Cache off because the problems with the cache not flushing was causing people to leave 2 comments.

I recommend that all WordPress users implement this fix, as well as using my guide to add APC as well, as it will significantly speed up your page loading speeds, even if WP-Cache keeps updating because your site is receiving a lot of comments.

    Making SK2 and WP-Cache play together…

    I noticed today that WP-Cache wasn’t cleaning the cache whenever a new comment was posted.
    I remembered that Everton had the same problem earlier and he had found a solution to it.
    This didn’t seem to be an isolated case and it can be pinne…
