Facebook app permission issue.

Hi members,

I stuck in facebook app deveopement.
My app has permission to read email,public_profile and user_friends, but i want permission public_action to post message on wall.
I can post it from my account successfully.
but when any other user login into my application and try to post message than it requires permission.
I have requested for permission many times of publish_action, but all time facebook rejects my permission request.
it returns "The following items were not reviewed due to general issues with your app:"
but my application is fully configured and it is live to use for all users.
What is missing part?

I have already read how to request for permission.
https://developers.facebook.com/docs/facebook-login/permissions

I have follwed those steps .but it doesn't work to approve my request.
Is anyone has been done like this before?
Any solution will be highly appriciated.
