Hello, How will a site work if both cache plugin for WordPress is enabled and the cache on Cloudflare enabled? Anyone have tested this? Cloudflare have three levels of cache to choose from. The most used is of course standard: No Query String: Only delivers files from cache when there is no query string. Ignore Query String: Delivers the same resource to everyone independent of the query string. Standard: Delivers a different resource each time the query string changes.
