to display all subpages and every effort I make at doing so ends up making this part of the sidebar not show up at all. I’m not versed with PHP code really so any help is greatly appreciated. I just want to add on whatever code I need to properly after what I already have in order for it to show all subpages 3-4 levels deep. Again thank you for your time.
By default, WP shows every children/subPages, all levels.
However, if you are using widgets for your sidebar – the editing of the code is irrelevant: the template tag is coming from the widgets, not from your sidebar’s code.
