I have a self-hosted private music collaboration site where my friends and I can upload files and then enter a quick shortcode to that file in a comment so others will be able to access it and work on it.
Here's the problem. Right now, when you type in a shortcode, it isn't parsed into a link as it is within posts and pages. I was told to use the function:
add_filter( 'comment_text', 'do_shortcode' );
...but I honestly have no idea which file I need to add that line to or if that's really the solution. Any noob-friendly instruction will be appreciated!
