Ahhhh Thank you albert, so I am looking and there are a lot of options to select, in this case where I am trying to allow access to the url in the screenshot, which component would I select? Also will this work also for multiple sites or I have to create this rule separately for each one under each domain?
Allow who/what? Cloudflare allows all URLs by default. Security features can block requests if they appear suspicious. The exact error page your are getting will indicate which feature is the cause. This will tell you which feature to skip.
Okay I was advised by someone to allowlist /wp-content/plugins/litespeed-cache/guest.vary.php for the litespeed plugin for ‘guest mode’ to work properly that there appears to be a firewall blocking it. I allowlisted this url above in my security plugin already - then was told to create a firewall rule for it in cloudflare.
