"Problem in blog posting" from Writer

Hi,

Several months ago, I began getting a "Problem in blog posting" error when I click the Publish button in the Blog Post dialog.

I'm using WordPress 2.0.1, hosted by a 3rd party (NetFirms).  It's configured to use the "metaWebLog" API and an URL of (my domain)/xmlrpc.php.  I believe the PHP script is still working OK - I can retrieve the categories from my blog.

Is there any troubleshooting I can do, or a log that would give me more information about the error?

Thanks,

Dan.
