The RSS feed may not be constructed with valid HTML tags to create the link. Check the raw XML of the RSS feed by navigating directly to the RSS feed in Firefox or Google Chrome.

This is an example of a valid RSS feed link:
[CDATA[This is a <a href="">link</a>.]

This is an example of an invalid RSS feed link:

Note that the <a href></a> is missing from the invalid example. Internet browsers may render the RSS feed correctly, but Blackbaud NetCommunity will interpret the link as plain text and attempt to create a link using the primary site URL located under Administration > Sites & settings.

You can check the validation of the RSS feed by using a third party feed validation service. Please click here to visit the validation service located at W3C
