Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Could you please check whether your server is running an updated PHP version ie at least PHP 7.0? You may need to get in touch with your host to get this information and if the version is outdated, please ask them to update to the latest stable version.
Looking forward to helping you. Thank you.
