You may have noticed that we've had this problem on this blog on and off from day one. Incredibly annoying because we haven't gotten the praise that we have earned and that motivates us so immensely... :)

The solution: Make sure you have a URL and a language configured on the uBlogsy landing page or higher up in the hierarchy. Right click the node, it's under "manage hostnames".

We currently use English, but I suspect any other language will work just fine as well.

Presumably, uBlogsy does some langauge-related stuff when a comment is posted, and barfs when no umbraco language is defined (in my mind, there ought to be a default somewhere, but maybe not).

And don't ask me how I came up with the idea to make that change - I honestly don't have even a hint of a clue. Divine inspiration, perhaps... :)

Caveat: This fix was implemented ten minutes ago... so... I have no proof that it works longer than that.
