第一次发帖子，不能截图好像，粘贴下 tophub.today 的错误：
Internal Server Error
MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error. [/home/www/i/tophub/vendor/bcosca/fatfree/lib/base.php:2633]
随后在 isitdownrightnow.com 搜了下 tophub.today，返回 down for everyone.
（至少别给外人看见服务器的错误信息啊？还是说被 hack 了？）
