How grant acces to pages also?

This plugin was intended for posts only. If you wish to use it for pages you need to add that feature to wp_jv_prg_posts_where_statement function. To function properly you might also would need to change other functions as well. I might consider adding such feature later on if the plugin become popular.

I just added this feature to the v1.6 of the plugin. You can use it same way as you setup for a post. Go to Pages -> All Pages and edit an existing page or add a new one. Select the reading groups you want to display the page to and publish it as a private page.

Thanks a lot I will try
