Hi there! We inherited a site on the Umbraco framework from a developer that is no longer in business.

They had previously created a custom RSS macro that styled our event feed pulled in from an off-site source. Recently, however, that functionality broke, and I've been struggling to figure out why ever since.

We patched together a workaround and used a different RSS generator, but we'd really like to know what went wrong with this one.

As far as the macro is concerned, all I can find that is related to the event callback is below. The RSS url is pulled in via a field on our top-level site identity, https://www.alumnionline.pitt.edu/controls/cmsv2/components/rss/rss.aspx?sid=1729&gid=2&calcid=1419&pageid=637.

The RSS feed is functioning just fine and works well with other generators or scripts, so that leads me to believe there's something wonky going on with the code below. Any ideas are appreciated! Thanks!
