It sounds as though the particular location in which you're trying to publish your blog may not be in our database. Can you let me know which location it is so I can investigate further? If so, you can post that information here or feel free to send it to me via my profile.
In the meantime, I suggest that you post your blog in a wider location - the state you're in for example if you're attempting to post within a city - or you can always select All Locations. You'll then be able to update the blog location at a later time once we get things sorted out.
Thank you for making us aware of this.
