Hi Desi,

I've tried to replicate this issue on our end (posting blog post from backend) seems the links generated correctly.
Is it possible for you to provide us with the back end, FTP access to your site and your twitter login credential to check on this issue?

You can add the information needed by edit your first post in the Details section or you can just include your site's access once at http://stackideas.com/dashboard/site rather than needing to keep adding them in your replies
