Hello, I have a problem with cach on my subdomain, sometimes works old code, what can I do to avoid this trouble. How can I turn off the cach only on subdomain?
Create a Page Rule:
Add Setting: Cache Level (Bypass)
Make sure it’s the first Page Rule in the list.
How can I add the page? I suppose I can create the page with the button Add site and page will be in list where domain is.
You should create what @sdayman suggested in the page rules tab of your Cloudflare dashboard.
