Fatal error: Cannot redeclare directory_theme_paginate()

Finally, disabling my child theme fixes the error but leaves me childless. Sorry for the many posts.

I thought you guys did that, since I see the 2017 theme became active a few hours after I left the office. If you check now, you can see what happens if I activate my child theme.

Okay. After reverting to Directory-Starter 1.1.5, I removed a section of code in the child theme’s functions.php which seems to have fixed much of the site. Here is the removed code:
// Define the version number for quick access
if (!defined(‘DIRECTORY_STARTER_VER’)) define(‘DIRECTORY_STARTER_VER’, ‘1.1.5’);

require_once(‘lib/utils.php’); // Utility functions goes here
require_once(‘lib/config.php’); // Configuration goes here
require_once(‘lib/init.php’); // Theme setup functions goes here
require_once(‘lib/cleanup.php’); // Cleanup functions goes here
require_once(‘lib/scripts.php’); // CSS and JS includes goes here
require_once(‘lib/nav.php’); // Nav menu functions goes here
require_once(‘lib/sidebars.php’); // Register your sidebars here
require_once(‘lib/widgets.php’); // Widget functions goes here
require_once(‘lib/comments.php’); // Comments functions goes here
require_once(‘lib/entrymeta.php’); // Entry meta functions goes here
require_once(‘lib/custom.php’); // Any custom functions goes here
require_once(‘lib/gd.php’); // GeoDirectory functions goes here
require_once(‘lib/admin/customizer.php’); // Customizer settings
require_once(‘lib/styles.php’); // CSS generated by customizer
require_once(‘lib/dummy.php’); // Dummy post functions goes here

Leaving any “require” line breaks the site. Without them, the search function of the directory works, but my category pages are crazy. i.e.:
Looks wrong: https://montclaircenter.com/apparel-accessories/apparel-accessories/
Should look like: https://montclaircenter.com/?geodir_search=1&stype=gd_shopping&s=+&snear=&sgd_shoppingcategory%5B%5D=&sgeo_lat=&sgeo_lon=

I’d really appreciate it if you’d help me find a fix or how to revert this issue. I haven’t completely checked over the rest of the site yet, but so far i might be able to redirect all category page links to similar searches as a workaround (hopefully you’ve got something better). I still want to perform the theme update and soon the WP 5.0, but stable first.

Thanks again for the help, any advice here would be great.
