我刚升级了我们的服务器，它有最新版本的php。当用户尝试登录我们的网站时，我们收到以下错误：
The staging.ilovenz.me page isn’t working
staging.ilovenz.me didn’t send any data.
ERR_EMPTY_RESPONSE
我检查了日志文件，我们遇到以下错误：
[28-Feb-2017 22:23:33 UTC] PHP Warning: in_array() expects parameter 2 to be array, boolean given in /mnt/stor14-wc1-dfw3/staging.ilovenz.me/web/content/wp-content/themes/kleo/lib/options.php on line 2416
在查看2416行的文件后，我可以看到以下功能，我不知道该怎么做...有些帮助会很棒！
