WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Theme customizations not showing., by t-p I have tried purging the browser and the wordpress cache. Also try: – Flushing any caching plugins you might be running, as well as server caches, any op cache or content network cache as well such as Cloudflare. – Flushing Managed host caches. Managed WP hosting often has special caches. If your host has a “Purge Varnish” or “Flush Memcache” tool, try that. You can ask your provider to flush memcache and Varnish for you if necessary.
