 * Sorry, but the plugin doesn’t tested with standalone bbPress. Let me some time
   to test, I will notice you here as I finish.
 * Thanks for the feedback!

 * Hi again,
 * It looks like last stable bbPress version doesn’t has standalone installation.
 * So, do you use bbPress prior 2.0? Can I have your bbPress version?
 * Thanks!
