应用程序几年后无法运行
我已经拥有一个应用程序很长时间了，每天有几百人玩它，但我不再积极进行 Facebook 开发。
今天我收到一堆电子邮件抱怨它不再起作用，果然它只是一个空白页。
我不想重写任何东西，只是在寻找我能做的最低限度的事情来让事情顺利进行。
我不想升级我的 Facebook 库。我使用 $facebook->require_login() 这似乎是问题所在。
它是一个 FBML 应用程序，查看源代码显示它已输出正确的 JavaScript 重定向，它只是什么都不做。
以前，我在应用程序设置中关闭了一些选项，以纠正不断更新造成的其他问题，但现在似乎他们不再提供该选项。
I have had an app for a long time now, there are a few hundred people who play it daily but I no longer actively do Facebook development.
Today I got a bunch of emails complaining it no longer works, sure enough it's just a blank page.
I don't want to rewrite anything and am looking for the bare minimum I can do to get things rolling.
I have no desire to upgrade my Facebook library. I use $facebook->require_login() which seems to be where the problem is.
It is an FBML app and viewing source shows that it has outputted the correct JavaScript redirect it just simply does nothing.
Previously I had turned a bunch of options off in the app settings to correct other problems created by constant updates but now it seems they no longer give that option.

https://github.com/facebook/php-sdk/blob /master/examples/example.php 是您需要了解的所有内容。
我没有简单地升级一些功能（一些 fql 查询等），因为它们对应用程序并不重要，尽管我认为这不会花费更长的时间。
不到一个小时就可以开始工作了。
https://github.com/facebook/php-sdk/blob/master/examples/example.php is about all you need to know.
I didn't upgrade some functionality (some fql queries etc) simple because they are not critical to the application although I don't think that would take much longer.
Less than an hour to get things rolling.
