Not working for me neither. I’m not even sure when it stopped working.I pretty much came to rely on it to post to my Myspace blog and to post to all three supported sites when I edit a post.
Unfortunately, I don’t think there are any alternatives that crosspost directly to the myspace blog. If anybody reads this and knows of one, please let me know!
The author of this plugin has been MIA for a while. His site hasn’t had any updates in several months. I hope he comes back and updates it someday or maybe someone else will. Wish I had the expertise to get it back to operational myself 🙁
