(cURL error 60: SSL certificate problem: unable to get local issuer certificate)
Other Information
(I installed the “WP-Optimize” plugin in wordpress. I wanted to enable gzip compression in the cache section but this error shows up. Does this have to do with a cloudflare ssl and how can i fix this issue?)
Not necessarily. When you try to access an external host from a site hosted with us, it’s checked against our own nameservers first before being sent across the internet. Seeing how your own domain is hosted by us, that means that requests from your own site go directly back to our own servers and do not pass through Cloudflare.
This also means that any SSL certificate you have on Cloudflare do not affect requests from your own site.
In short, loopback requests (where your own site talks to your own site) don’t work here, and plugin features that involve checking the generated content of pages won’t work because of that. But these features are rarely necessary for a site to work.
Rest assured that you don’t need a plugin for gzip compression. Our servers do that by default, and Cloudflare does excellent compression by default too. So there is no need to worry about that.
