It's never a good idea to downgrade CMF. But on the over hand Plone 
1.0.x doesn't work with CMF 1.4.x.

Your portal_url object in the root folder of your site 'knows' if it is 
a CMFCore.URLTool or a CMFDefault.URLTool. You could delete the 
portal_url object ('CMF URL Tool') and add a 'Default URL Tool' instead.

Don't know. There might be other things broken, depending on the date of 
your checkout.
