ssl certificate

i recently got comodo ssl certificate, i pasted it in ssl panel but when i click upload certificate it showing the same page,i don’t know whether my certificate is installed or not. my browser showing that my site redbuzz.ga is not secure. please help me.

I just checked https://redbuzz.ga but I see a green lock. If you don’t see it yet, please try clearing your browser cache, because some browsers (notably Chrome) remember certificate statuses for a while.
