Facing the problem…and the old version of the plugin was deleted automatically.
Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
It is possible that there were some left over files during the update which is causing this error. Please login to your sites via FTP and manually delete the “seo-by-rank-math” folder from the wp-content/plugins directory and then perform a fresh install by heading over to Plugins > Add new
PS: No data loss should be experienced in this process.
Looking forward to helping you. Thank you.
