Clear Server Cache

I’m getting an issue with my site. I was rewrite some .php and .css files and uploaded it in client area. When i visit my site the previous css files only displayed. I checked everything and cleared my browser side cache also. But nothing happened. Then I completely delete my root folder and uploaded but no change. What is the problem and how can i delete server side cache?

Thanks in advance.

There is no cache on our servers. However, I see you are using Cloudflare. One of Cloudflare’s jobs specifically is to cache static content. Try clearing your Cloudflare cache instead.
