Hi, Earlier i have added few page rules for my website(pro plan) and some time ago my cloudflare plan was downgraded to free plan. So my page rules got deleted now & i dont remember the exact rules which were added. I upgraded my plan to pro yesterday. I would request you to provide the list of page rules which were there when my plan was pro.

Depending on the time period you are describing, that information may no longer be available. I would start by checking your audit logs.
