Hello, I must say that I didn't check my dashboard often, so I only recently noticed that in the past months, my Cache Miss Rate went to a high number when it previously stayed at below 5%. I can't seem to find a way to fix it? I searched around the Forum and tried to activate the Override Cache Control Headers yesterday, I hope that does help? Or should I also deactivate my other caching plugin?
When I checked the Top Cache Miss Reason, the error shows: disallowed vary header values are present.
Does anyone with a little more knowledge have any suggestions? Cache hit rate is now pretty much 3%
Let me know if more info is needed.
Thank you in advance and sorry if I may bother you a few more times!
