I have recently updated two different blogs to WP 2.7. Both are running on separate sites with different themes.
In both cases the Comments RSS feed no longer validates. When I submit my feeds for validation, I get the same error:
XML parsing error: <unknown>:18:51: not well-formed (invalid token)
Both were working prior to the update. Is there any possibility that it is a problem in the new coding?
Any help would be appreciated.
