Let me quickly revise one thing I said and make sure you will not encounter any problems soon.
This often makes sense, but seems not to be the case with Kajabi!
I just had a read at their Docs and they recommend NOT to proxy the CNAMEs.
So please turn off the Proxy and use CloudFlare with Kajabi in DNS only mode.
This docsumentation site is btw a good help to configurate the rest of the CLoudFlare settings. If you scroll down you will see many more help at what SSL mode to chose and what PageRules to set up
Hm but lower down (at troubleshooting)
They provided a Screenshot where they again used Proxy mode.
May on this one they should be really clear on what not! So maybe it works with
aswell but is at least not recommended officially…
Dont like that they are not very clear on that.
