XF 1.3 Only secure content is displayed (Cloudflare's Flexible SSL)

[Minecraftly]

I get the browser warning of "Only secure content is displayed" while browsing my website via HTTPS.

I use Cloudflare's Flexible SSL and managed hosting.

What are the steps that can be done to fix this problem?

Use your browser console to inspect what are those insecure resource/content.

Is there any plugin to force relative path or something like that for Xenforo?

You have to manually modify your resources, use // instead of http://.

I couldn't figure out how to do that. Do you know how sites like @digitalpoint do that while still having Cloudflare's Flexible SSL?
