Category Order could not understand your category HTML. Please do the following:

• Disable all plugins except for category order to see if some other plugin is causing the problem. If the problem goes away, re-enable each plugin until you find the incompatible one.
• Try switching to a different theme, like the WordPress default theme.

Once you have tried the above steps, email david@coppit.org with the results of these debugging steps. Also include the following information:
