Hi there! I inherited a site using Umbraco that we're currently in the process of redesigning and moving. The current site was redone a few years back by a pretty shoddy third-party developer that just up and disappeared after the project was done well before I was hired by my company.

So, the last of my two years has been spent trying to fix the issues this developer left behind; some have been easy, others are super weird and confusing. Full disclaimer, I'm generally a Wordpress, Drupal, or Joomla developer and while, I've learned Umbraco just fine over the last few years, it's still not my first language, ya feel me?

This morning one of my colleagues let me know that the macro we use to pull in our flickr galleries on a page on our website "isnt working". I get to the page and see the "Error Parsing XSLT" language there.

The language from the developer is below, and it looks like the macro asks for an api key and user id in the content side of things. I've never had to mess with the flickr api, nor have I had to work with this particular macro, so any help at all would be great!
