I'm still not sure what this mean to be honest. I've checked that page, copied that code, added it into my site. And nothing has yet to change. I've gone back through it several times and I'm just not sure what the issue is or what exactly I need to add. It was filtering categories and tags just fine, but wasn't recognizing any newly added tags or categories. Once I deleted the old tags and categories, the code just stopped working. I tried duplicating the website as well, having Blog posts without external links, and starting over, and nothing is working.
