Hi - When adding a script (apex chat in this case) to the header within functions.php (pro-child) it then breaks pro editing or customization, but the script works fine on the front end. Guessing I am doing something wrong or missing something. Thank you for your time.
Receiving the following error when editing a page or customizing with Pro:
WARNING: You are viewing this page in an unauthorized frame window!
function add_head_script() { ?>
<?php } add_action( 'wp_head', 'add_head_script', 99 ); ?>
