I don't see any text in your blog either. I see two entries, one as a blog post, and one as a 'page' post, and both are just titles with no text. The blog post was unpublished and was saved as a draft.
I just entered the word 'test' in the body of the blog post and published it and it appeared on the blog.
Try this - When you create the post, there are two tabs on the text field. One is labeled Visual, and one is labeled Code. Try to make a test post once using Visual, then make another test post using Code. You can delete the tests posts afterwards. Please let me know if one works. If not, then we'll try something else
The only other thing I can think of is that your firewall may be preventing the transfer of information. We'll check other options if this doesn't work.
