debug on

just out of interest to avoid seeing errors with debug on
i’ve added “@” to the following lines
changes nothing, just hides the errors

line 41 if (@$option[‘desc’])
line 43 switch (@$option[‘type’]) {

line 88
if(@!$args[‘post_type’])$args[‘post_type’] = ‘page’;

line 172
if (@$page_info[$page->ID][‘show’]) {

line 176
if (@$args[‘child_of’]) {

line 213
if (@$instance[‘menu_order’] == ‘yes’) { // Deprecated, eliminated upon form display (see below)
