Website URL: justinslab.great-site.net
It just redirect me to /?z
It works on my phone, but just on my phone.
Update: I don’t know what I did, But I works now.
?z is just a IF security program to help protect your site. It does not affect your site at all.
I think it’s this issue:
The ?z is not actually a security system but part of a domain parking service which is used on unused subdomains.
