We have found a bug with the way we set up Blogger accounts. Essentially, if your Blogger account does not have an avatar set, Flock cannot configure the account correctly. There are two ways to remedy this
1: Set an avatar for your Blogger account through the Blogger options
2: Open the blog editor and click on the Configure button (the wrench and screwdriver). Then click on the Add Blog button in the resulting dialog and set up your blog that way.
We apologize for the inconvenience this creates, and we will have this fixed in our next incremental release.
