Comments blocked when using WP Super Cache
September 28th, 2009 by Michael Hampton
I am currently investigating an issue where users of Bad Behavior on WordPress, who also use WP Super Cache, have readers who are unable to leave comments on certain posts. Bad Behavior may block these requests with a technical support key ending in xxxx-xxxx-b40c-8ddc.
A preliminary investigation shows that this is likely a problem with WP Super Cache not removing expired data from its cache in a timely manner. (The current version 0.9.6.1 was tested.) This issue seems to affect both “full on” and “half on” caching modes. Currently the only known workaround for this issue is for the blog owner to manually delete the contents of the cache at least once every 48 hours.
I will post with further information as soon as I determine more precisely what the conditions are in which this problem can occur and consult with the author of WP Super Cache on possible fixes. For more technical information, you may visit this WordPress.org forum thread.
Update: This was confirmed to be an issue with WP Super Cache. A fix is included in version 0.9.7 of WP Super Cache.

I use “Intense Debate” for my blog commenting. So far, your “bad behavior” seems to work just fine with WP Super Cache’ operating in conjunction with I.Debate plug-in.
Hope this helps.

We are running 0.9.7 and had it happen this morning. One of our regular users got the Error 403 and a technical support key that leads to http://www.ioerror.us/bb2-support-key?key=xxxx-the-key-num
They were logged in as an Author, it happened on two machines a home pc, and a work pc with McAfee and a corporate spyware program.

After updating WP Super Cache, all your users will need to clear their cookies, or they might continue getting the same error on some pages.
