Adding a tab to a fan page does not work… error: (#210) Subject must be a page
问题 I'm trying to add a tab to a fanpage using the graph api/PHP SDK and I'm receiving an error : (#210) Subject must be a page I've tried using both the user access_token AND the page access_token but neither work. I've tried using the page id of numerous accounts and still no go. Here is my code: <?php $path="/PAGE_ID/tabs/"; $access_token="ACCESS_TOKEN"; $params = array( 'app_id' => "APP_ID", 'access_token' => $access_token ); try{ $install = $facebook->api($path, "POST", $params); }catch
