RSS Validation [xmlns issue]

Hi,

I’ve run into an issue similar to what was noted
here, but am unable to resolve it.

Currently using WordPress 2.32 as well as Podpress 8.8 for a podcast. My feed is here. When validating via feedvalidator.org, I get the following:

Sorry

This feed does not validate.

line 7, column 77: XML parsing error: <unknown>:7:77: not well-formed (invalid token)

The line in question seems to be:

xmlns:creativeCommons="https://backend.userland.com/creativeCommonsRssModule"xmlns:itunes="https://www.itunes.com/dtds/podcast-1.0.dtd"</p&gt;

I’ve reloaded my feed-rss2.php (my WordPress is a 2.3 to 2.32 upgrade), but still no luck. I expect this is a fairly simple fix, and appreciate any guidance. Thank you!
