WP_User_Query Fatal Error

Further testing reveals that the actual page in question where I am encountering this error (mysite/wp-admin/users.php) gets as far as line 335:

$wp_list_table->prepare_items();

When the myCred plugin is active, the users page parses up to that line then everything grinds to a halt with the aforementioned undefined method error.

Hi

Thank you for reporting this. Looking at the WP_User_Query documentation it seems the get method was introduced first in WP 3.5.

I will look into adding some fix for older WP versions.

Delete your current myCRED installation and re-download + install to resolve this issue.

Alternativly if you do not want to loose existing log entries you can open the mycred-admin.php file in plugins/mycred/includes/ and on line 143 replace the existing sort_by_points() function with the following:

/**
 * Sort by Points
 * @since 1.2
 * @version 1.2
 */
public function sort_by_points( $query ) {
	if ( !is_admin() ) return;
	$screen = get_current_screen();
	if ( $screen->id != 'users' ) return;

	if ( isset( $query->query_vars['orderby'] ) && isset( $query->query_vars['order'] ) && $query->query_vars['orderby'] == 'mycred' ) {
		global $wpdb;

		$cred_id = $this->core->get_cred_id();
		$order = $query->query_vars['order'];
		$query->query_from .= " LEFT JOIN {$wpdb->usermeta} ON ({$wpdb->users}.ID = {$wpdb->usermeta}.user_id AND {$wpdb->usermeta}.meta_key = '$cred_id')";
		$query->query_orderby = "ORDER BY {$wpdb->usermeta}.meta_value+0 $order ";
	}
}

Excellent!

The above changes worked like a charm! Thank you for your prompt and efficient support!
