Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. https://crt.sh/?q=example.com), so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

And your https doesn't work:
Fatal error : Call to undefined function trailingslashit() in /home/ziji2015/public_html/wp-content/plugins/lfjmonetizeme/options/defaults.php on line 0
Yes, I use Hostgator and tried for the first time to install SSL onto a domain that I’ve had for years.
I was unsure after getting the SSL process into action when seeing the error message saying that the certificate expired and therefore, have not pressed the “install” button yet.
Please don't...
Please login to your cPanel. (cPanel, the port ends in 3083) instead of your WHM.
In cPanel, there's a choice said "Manage SSL/TLS Certificates" or "AutoSSL" feature.
Or you can use the below tutorial to run AutoSSL (request certificates) for all users.
