I've had the domain zbz5.net for some years now, even though it's been just a holding page for most of the time before I started this blog. Occasionally I've been using it for testing purposes though, and this is the source of my agony.
I was testing out HelpBurner and its capability to post directly to Drupal. I did not get it to work, and in the process of finding out why, I opened up the Blog API module for anonymous users (just a test site, remember..)
