I'm using WordPress, DNS is CloudFlare.
When I enter my site seo.whoops.com.tw, it will get mixed content, but I have used Auto SSL Rewrite by CloudFlare, also I installed real simple SSL of the plugin, but the issue still exists.
After that, I check the reason is due to the theme main CSS using ../image.jpg as path and the site is catching HTTP:// not https://, but I really don't know how to fixed it（I know I can just change path with fixed URL, but due to updated after, I don't want to.）
I just notify the theme author and they say it's not wrong, so I came here to ask someone who can give me a tip.
Thanks.
