Can't Reblog

I attempted to reblog from another persons post. When I clicked the reblog button I received a message that the reblog was completed, however, when I checked it did not show on my blog. A couple of other bloggers reposted the same article and it shows up on their blog.

I did go back to the original blog and it told me that it had already been reblogged.

Any idea whzt may be going wrong?
