After updating to 2.7 on different blogs, my comments feed is no longer valid. Feed Validator gives the following error:
XML parsing error: <unknown>:18:51: not well-formed (invalid token)
I took my investigation to another level and tried to add the feed to a feedburner account. Feedburner gives a more specific error:
The URL you entered does not appear to be a valid feed. We encountered the following problem: Error on line 18: The reference to entity "cpage" must end with the ';' delimiter.
<b>Because the error refers to the link to an actual comment, the WILL validate as long as there are NO comments.</b>
BUT... As soon as a comment is added to the blog, the error shows up.
This is happening on two different domains, which are running two different themes.
Is anyone else noticing this issue after updating? Any chance it is a bug in the new coding?
