Well maybe I'm doing a silly mistake, but I have created two jobs, and I can see them listed in the admin area.
I have edited the default page created by job manager, to be nested to another and I still see the sentence:
"Hi! This page is used by your Job Manager plugin as a base. Feel free to change settings here, but please do not delete this page. Also note that any content you enter here will not show up when this page is displayed on your site."
I suppose I need to do anything else, but I can't figure out.
Sorry if this has been asked before, but I haven't find anything similar in the forum.
