Fatal Errors changing after changing functions.php

    Hello, I’m a PHP/Javascript developer with some experience with WP, but I was called in on an emergency by a friend to help fix errors in their current WP site which is built on some crazy theme by this guy:

    dressyourwp.com

    I figured out that the problem is in the version of jQuery being used, so I attempted to add the jQuery migrate to the registered scripts by doing the following change:

    // Add RSS links to <head> section
	automatic_feed_links();

	// Load jQuery
	if ( !is_admin() ) {

	   wp_deregister_script('jquery');
	    wp_register_script('jquery', ("http://code.jquery.com/jquery-1.10.2.js"), false);
// ADDED THIS LINE ONLY
	    wp_register_script('jquery-migrate', ("http://code.jquery.com/jquery-migrate-1.2.1.js"), false);
// END OF EDIT
       wp_enqueue_script( 'jquery.colorbox', get_bloginfo('template_directory') . '/js/jquery.colorbox.js', array( 'jquery' ) );
	   wp_enqueue_script("prototype", get_bloginfo('template_url') . "/js/prototype.js");
	   wp_enqueue_script("scriptaculous", get_bloginfo('template_url') . "/js/scriptaculous.js");
	   wp_enqueue_script("glider", get_bloginfo('template_url') . "/js/glider.js");
 wp_enqueue_script(" validation", get_bloginfo('template_url') . "/js/ validation.js");

	}

    When I uploaded ONLY THAT ONE CHANGE. The entire site now says:

    http://www.albanco.com/

    Fatal error: Call to undefined function automatic_feed_links() in /data/…/htdocs/wp-includes/functions.php on line 4

    I removed that line and uploaded the original functions.php and have the same error… I have no idea what happened or how it happened, but now a simple fix for a big problem has turned in to a MAJOR problem that I can’t seem to figure out.

    I’ve commented out the automatic_feeds_link() function and then another function throws the same error… it’s like editing this single PHP file caused it to “recompile” and break the entire build… which doesn’t make sense since I was under the impression PHP didn’t compile.

    Because of the complexity of the theme and the fact that I didn’t make it, I’m really apprehensive about removing it or changing anything else.

    Can somebody please explain to me what happened? The Theme was loading up fine, i made no other changes… how can a single line (which is then removed) cause such destruction?

    I’m not looking to mire myself again by attempting to upgrade their WP with this shoddy theme and unknown plugins

    Good for you! 🙂

    I feel like WP support requires such esoteric, non-PHP specific knowledge

    In what way? WP just uses boring old PHP but like every other CMS out there, it just has its own pre-built custom functions & filters.

    I doubt I could contribute more than noise

    Oh – you’d be surprised how many support topics we deal with where we have to try and talk someone through using FTP or what a server error log is or the fact that it can take up to 3 days for a new domain reg to fully propagate. And that’s not even taking into account the ton of basic CSS issues that are posted. Pretty basic stuff. 🙂
