I’m new and a non-specialist so please excuse me if this has an obvious answer.
My developer made some improvements to my website. However, after using GTMetrix to look for SEO optimisations, it seems the changes were not being reflected due to the cache.
After ‘purging’ the cache on Clouflare, this has solved the issue.
However, Cloudflare settings are set to 4 hours before cache expiration, yet we had the same issue on GT Metrix for over a week, until I purged the cache manually.
Why was it not refreshing?
