Hi, thank you for your quick answer!
1. We had the official plugin installed, yes. We deleted both and only installed the Super Page Cache now. Test Cache now shows: “Page caching is working properly”, but on GTmetrix and website headers it still doesn’t seem to cache properly?
2. The APO was never enabled, as we haven’t purchased the APO and have no subscription for it (it was greyed out in the Cloudflare dashboard settings). Maybe the official Cloudflare plugin created this problem earlier?
3. We are working on contacting siteground for the server level caching, couldn’t reach them yet.
4. We only have one rule “Cache Everything”. https://imgur.com/MYHnJq5
Thank you so much for your help!
