Error message when clicking over

[Dean Landsman]

People coming to my page today report that they are seeing the following:

Sorry! There was an error: The attribute "allowDirectoryListings" must be
true.
The error was detected by Frontier 9.0 in mainResponder.respond. Webmaster:
support@weblogger.com. Time: Tue, 27 May 2003 18:15:49 GMT.

How do I fix this?  Or is this one of those "out of the blogger's reach"
issues?

Thanks in advance.
