bug in the redirect code when searching using WIF key

go to any page.,

https://www.allbitcoinprivatekeys.com/

select last Private key on the page and click + sign beside that,
which redirects using private key to its location on page.,

it will redirect you to current page + 1. i.e. next page instead of the page where the private key entry is listed

sorry for my bad english.

e.g.

go to

https://www.allbitcoinprivatekeys.com/warning:understand-how-this-works!/5HpHagT65TZzG1PH3CSu63k8DbpvD8s5ip4nEB3kEsreR42AY81

its last private key on 1st page., but you will end up on page 2.
and there is no entry of private key.
