Hi, Ive installed the pay per view plugin, Ive disabled the for all posts for global settings, and I want to apply it to selected posts. Ive applied it to The Jungle Book Official Teaser Trailer on the site. Im using wpzoom and it not applying to the post, Ive selected in the widget of the post the settings as attached, but it doesnt work, ive also added content and excluded wpzoom, I get the button for 20p I go to paypal it takes the money, sends me back but doesnt show what is in the main description which is suppose to be allowed?, do you have a manual I can look at? can you help?
