I'm setting up a child theme for Ryu, and everything was going well until I tried to change template-tags.php (there's some meta content I wanted out). The changes I made weren't taking, and after a bit of research I found I had to point to it. It gets called in the functions.php. So I tried using get_template and later get_stylesheet, and I tried putting it in the header and in a new functions.php, but all I got was a blank screen when I reloaded a page (in fact, just by putting functions.php in the child theme directory, I got a blank screen.)
Any idea on how to correctly point to template_tags.php?
