Due to the automated nature of Let's Encrypt™, the certificates have 90 day validity. However, this is not a problem, because renewal is automatic and does not require any human action.
Only DV (domain-validated) certificates are available. This is because the validation for EV certificates cannot be automated, and is therefore not in scope for Let's Encrypt™.
Wildcard certificates will be released as part of the plugin once the ACME v2 spec is live. This is slated for Jan/Feb 2018.
Yes. We test this plugin with CloudLinux + CageFS and Litespeed Web Server Enterprise environments. There are no known issues or caveats of any kind. There is no requirement to include any additional files in CageFS skeletons.
If the domain is "proxy-enabled", i.e requests go through Cloudflare before they come to cPanel, then the plugin will have no effect on visitors for that domain.
This is because Cloudflare is terminating the SSL instead of the cPanel server. At most, the benefit would be that you could implement the "Full (Strict)" mode of Cloudflare, where the Origin<->Cloudflare PoP connection passes x509 verification.
No, it is not. The principle value proposition of this plugin is that it allows the end-user (the cPanel user, rather than the cPanel/WHM administrator) to issue whatever certificates whenever they want.

We will NOT be offering buyer's remorse refunds under any circumstances. We provide a trial for evaluation purposes, and you should perform all testing during this trial period.
If you require more than 72 hours to test the plugin, please contact support for a longer-duration evaluation.
For all other refund-related enquiries, please contact support.
