So, I was trying to update one of my personal plugins. I'm trying to apply a filter to the_tags filter with this code.
I know I got that right but I can't seem to make it work. No filters are being applied to the_tags. On the other hand, it works well with wp_tag_cloud. Anyone knows if this is a bug or something. And aside from tinkering with category-template.php, is there a way for me to force lowercase in my tags?
