My domain is: overloadromania.ml
My web server is (include version): nginx
The operating system my web server runs on is (include version): windows 10
My hosting provider, if applicable, is: infinity free
I can login to a root shell on my machine (yes or no, or I don’t know): i dont know
I’m using a control panel to manage my site (no, or provide the name and version of the control panel): infinity free control panel / cpanel epizy/ vista panel
I made a SSL check because I got this error in Facebook Sharing Debugger:
-Can’t validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.
The SSL Check said: The certificate is not trusted in all web browsers. You may need to install an Intermediate/chain certificate to link it to a trusted root certificate.
So I got a Chain Certificate from whatsmychaincert.com but I don’t know what to do with it. I dont know a thing in php/html etc etc, Someone please explain me step-by-step, if i m not asking too much
