Child theme - custom functions - mapping cp_login_head
I'm trying to modify something on the login link so I looked at the functions.php file, which is empty, but says to put all my custom functions there. So I go to the readme which says that cp_login_head IS a pluggable function so I browse to the includes/theme-functions.php file and grab the code I need, copy it into my functions.php file, and make my changes, and then upload my functions.php file to my child theme directory. The changes aren't there. Am I missing a step or doing something wrong? Everything else so far works (my mods to the direct child theme 1-to-1 mapped files). I could probably hard code this stuff into the header itself and just replace <?php echo cp_login_head(); ?> with the code, but that kind of defeats the purpose of a custom functions file yesno?
