My page is not loading some of the content that is on the page, such as CSS and JS. I am getting an error in the console: Failed to load resource: the server responded with a status of 403 ()
What steps have you taken to resolve the issue?
The only way to get rid of this error is to enable developer mode. Why is this?
You should be able to see the challenged or blocked event under the Security tab → Events at Cloudflare dashboard for your zone and know exactly which security option was triggered. Could be Managed Rules my best guess, otherwise Bot Fight Mode or Browser Integrity Check.
Once you find them, click on a particular one to find more details about it (user-agent, IP, HTTP version …). If yes, could you share some details which service was triggered that blocked you?
