PHP fatal error in wp-settings

Have you edited wp-config.php lately? I suspect your problem is there.

This should be the bottom of that file. There should be nothing afterwards:

/* That's all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
    define('ABSPATH', dirname(__FILE__) . '/');
require_once(ABSPATH . 'wp-settings.php');

What was the active theme?

@sterndata, I have edited the wp-config.php, taking cues from other support forum posts for solutions. This is what the bottom of my wp-config.php looks like:

define(‘WP_HOME’, ‘https://www.arhistoryhub.com/hub’);
define(‘WP_SITEURL’, ‘https://www.arhistoryhub.com/hub’);

/* That’s all, stop editing! Happy blogging. */

/** Absolute path to the WordPress directory. */
if ( !defined(‘ABSPATH’) )
define(‘ABSPATH’, dirname(__FILE__) . ‘/’);

/** Sets up WordPress vars and included files. */
require_once(ABSPATH . ‘wp-settings.php’);

@luke Cavanagh, I received the errors on theme twenty sixteen, theme twenty ten, and now on Education Hub free version theme.

Do you have any other references to ABSPATH there?

this version of the site seems fine.

https://www.arhistoryhub.com/hub/new_site/

When I go to https://www.arhistoryhub.com/hub/?cat=3, it all falls apart. is .htaccess there in the root of your site?

@butlercenter what is the current site url set as then?

There are no other references to ABSPATH in my wp-config.php

@sterndata, I have a redirect on the domain arhistoryhub.com to a non-WP webpage that is a landing page at arhistoryhub.com/new_site that links to the WP site at arhistoryhub.com/hub. Here is what the .htaccess reads in the public_html directory:

RewriteEngine on
RewriteCond %{HTTP_HOST} ^arhistoryhub\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.arhistoryhub\.com$
RewriteRule ^/?$ “http\:\/\/arhistoryhub\.com\/hub\/new_site\/” [R=301,L]

RewriteOptions inherit

# Use PHP54.4 Single php.ini as default
# Changed PHP handler from application/x-httpd-php54s to application/x-httpd-phpbetas on Fri Dec 18 00:45:34 MST 2015.
AddHandler application/x-httpd-phpbetas .php

# BEGIN WordPress

# END WordPress

@luke Cavanagh, my current site URL is https://www.arhistoryhub.com/hub

So the main menu item links are they post category links or page links?

The main menu item links are post category links, e.g.

Events

that is

“Events”

okay let me comment out so you can see what I am trying to say

Events
