 * Hello, I use Rank Math on all of my websites, thank you, it’s a very robust plugin!
 * I am hoping you could help me out with one website we’ve been trying to install
   on, but keep experiencing a “critical error” every time we try to activate it.
 * I’ve also tried to bring it into the website from FTP, and no luck.
 * Thank you!
 * Here’s the error:
 * Fatal error: Uncaught RuntimeException: Error saving action: Error saving action:
