I have a main domain and a sub domain up running with Cloudfare before and i found that my website of my sub-domain has so many problem.
Origin server: Godaddy Business plan
Purchased SSL from Godaddy already so i select “Full” mode in Crypto.
Changed name server from Godaddy to Cloudflare successfully.
I have a login function in my sub-domain. Everytime i tried to login, the sub-domain website prompts me a message telling i am logging in successfully. After that the page re-direct me back to the page where i perform the login function, and the problem comes, the website has just not logged in, it remains logged out status.
Any people can tell what have i gone wrong? Could i just disable CDN function to my sub-domain? Please guide me through, many thanks!
