I changed website and getting error

Dear team
Thanks for this amazing plugin
I am getting some issue with the plugin
I always do the website on my subdomain and when it’s ready, then I take it’s backup and restore on client’s domain. Last time, I installed your plugin on my subdomain and when I restored the whole backup on client’s website, Then your plugin kept the same key and giving error while scanning. Is there any option to reset your plugin? Or any other solution?
Waiting for your reply
Thanks
