Hi. 
You should remove this entirely:
When you use the button in CertSage to install your certificate into cPanel, CertSage enables the builtin HTTP->HTTPS redirect in cPanel, which is implemented at the vHost level, which is much more efficient and less error-prone than using rewrites. You can see this setting in action in the DOMAINS section of cPanel by clicking on Domains then expanding the section for the domain in question.
I have a strong feeling that you need to check this out as I suspect that your URL settings in WordPress have "http://" in them (rather than "https://"), which frequently contributes to this issue.
Another piece of advice (my opinion): don't ever use that third-party website ACME client (or anything like it). CertSage is a first-party ACME client because it is installed on your server and operates from there, rather than being installed on someone else's server and operating from there.
