It's primarily a social news site, but people do share programming problems.
What you have here is not a programming problem. You have a very specific issue with a particular third-party application. Whether it's a Magento bug, your own failure to read documentation, or a bug in your own installation, it's not intellectually interesting.
StackExchange (and similar sites) do a good job of giving you traffic from people who can solve your problem. Adding the post to HN is unlikely to help much, and it's not what this venue is used for.
