Since i Updated to 4.3.10 i have being getting error posting to facebook. i Keep getting the error message

Array
(
[Warning] =>
[Error] => (#200) If posting to a group, requires app being installed in the group, and \
either publish_to_groups permission with user token, or both manage_pages \
and publish_pages permission with page token; If posting to a page, \
requires both manage_pages and publish_pages as an admin with \
sufficient administrative permission
)
Array ( [Warning] => [Error] => (#200) If posting to a group, requires app being installed in the group, and \ either publish_to_groups permission with user token, or both manage_pages \ and publish_pages permission with page token; If posting to a page, \ requires both manage_pages and publish_pages as an admin with \ sufficient administrative permission )

To be clear, the admin has full permission and also we have manage page and publish page in the apps for the admin.

Is anybody having this problem and how do i fix it
