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', ("https://code.jquery.com/jquery-1.10.2.js"), false);
// ADDED THIS LINE ONLY
	    wp_register_script('jquery-migrate', ("https://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:

    https://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. ??
