刚安装WordPress插件Pretty Links Pro之后，在WordPress后台的仪表板上，就出现一个红色的警告大横幅，上面写着 ▼
Pretty Links Pro isn’t able to get critical automatic updates
You can retrieve or purchase a license key at PrettyLinks. com to enable automatic updates today.
After you paste your license key on the “Pretty Links” -> “Activate Pro” admin page, you’ll start getting automatic updates.
为何出现提示Pretty Links Pro isn’t able to get critical automatic updates？
如何去掉Pretty Links Pro警告提示呢？

- 打开Pretty Links Pro插件目录
