VK API. Why is there no access to the wall.post method?

Question

In contact with

I have one plugin that sends some information to the wall of the VKontakte group. The plugin runs on
javascript and posts everything as it should without problems, but pops up a pop-up every time.
I decided to remake it for php so that the script would work less stressfully for the user.
In scope I write "photos,wall,groups,offline,nohttps", as a result I get: There is

nothing about posting to the wall.
Well, as a result:

{"error":"wall.post. 15","error_description":"Access denied: no access to call this method"}

Although before that authorization was successful and the pictures were uploaded to the group's photo album.
Standalone application, everything should work. What could be the problem?

Answer 1

That's right, the method can only work through the confirmation window. The scope=wall parameter will be ignored in authorization for sites.

Answer 2

15 Access denied.
Make sure you are using the correct IDs and that the content for the current user is available in the full version of the site.
