Applets that work with the Wordpress service make it easy for you to cross-post and promote your content.
Here's a few things to double-check to make sure they work as intended.
Make sure XML-RPC is enabled for your WordPress blog
Make sure the username you have activated has full Admin rights
Double-check that the Blog URL is correct, and that you're running the latest version of WordPress.
If you’re still having issues , you can still trigger from your blog by using its RSS Feed with the Feed service.
