The channel owner should be an administrator or developer of your Facebook application. If not, there will not be a prompt for manage_pages. If you don't add the channel owner as an admin/developer, you will need to submit the application through the review process before your application will be able to properly request that permission from any user.I have started from scratch five different times in setting up my Facebook application and then setting up the channel in my Joomla backend. Each time I go to the front end of the website and login with my Facebook account, and I never see anything that asks for my permission.
