Cloudflare SSL and Multisite

I have a problem that I cannot fix. I also do not know if I need more pagerules(upgrade) for Cloudflare.

I tried everything in the forums and I could not get it to work. One time my image for my header would not work. Another time my sites would have the lock for the SSL but ONE of my mapped domains would not. My main site does not use the SSL unless I force HTPPS in cloudflare. If I change the DB options then I keep getting redirects for my backend for all my sites.

Is there someone who can do this all for me? Every setting I use does one thing right and messes up something else.
