Hello M.Freak,
Thank you for your reply.
Yes, my website was hacked. When I access my website from mobile devices, it was redirecting to porn website. My Web Hosting provider has fix that issue but I got this problem and they don't support me for third party template. I am not expert in Web Development so is it possible to provide more instruction. What I understand is, I download the template and replace the CSS folder then I have done that but same problem.
Could you please advise?
Best regards,
Chirag
