Custom taxonomies only throwing error

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'category' not found or invalid function name in /home/splitpea/public_html/staging/wp-includes/plugin.php on line 525

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'company' not found or invalid function name in /home/splitpea/public_html/staging/wp-includes/plugin.php on line 525

I get these three errors. I know it’s theme related and the category, company, and collections are all custom taxonomies I have attached to custom post types that are manually added (no plug-in). I’ve been Googling this for hours. The only thing I can figure is that I’m using some function wrong somewhere. Here is the code for line 525 if this helps anyone:

do {
		foreach ( (array) current($wp_filter[$tag]) as $the_ )
			if ( !is_null($the_['function']) )
				call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']));
	} while ( next($wp_filter[$tag]) !== false );

I don’t know what more I can say about the issue. I’ll be monitoring this thread in case someone has an idea of what I’m dealing with or need more information.
