Conflict with plugins that displays content in the admin area

Hi,

I found conflict with plugins that displays any post content in the admin area – i.e. WP Docs or Admin Help Docs. These plugins uses “the_content” filter, which is used also in Page Restrict.

In define_public_hooks() there is initiate_process_page() added to “the_content” filter chain, in the admin area too. To properly handle filtering “initiate_process_page()” should have one more line:

public function initiate_process_page($content)
{
    $restrict_process = new Section_Blocks();
    if(!is_admin()){
        return $restrict_process->process_page($content);
    }
    return $content;
}
