Hello @startechmarketing,
Thanks for contacting us and sorry for any inconvenience that might have been caused due to that.
Please note that we only report the 404s and unfortunately, we do not have information on how or why they are generated. You can get further insight into them by enabling the advanced monitor: https://rankmath.com/kb/monitor-404-errors/#advanced-404-monitor
That will give you more information like referrer and user-agent. You can use that information to track down the source or find out if it is just bots generating those errors.
You can fix these errors by redirecting them to a related page on your website:
Or you can exclude the URLs from WordPress Dashboard > Rank Math > General Settings > 404 Monitor: https://rankmath.com/kb/general-settings/#exclude-paths
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
Thank you.
