Hi Richard,
Thanks for your reply. Sorry the client asked me to turn off the site as it was unbearable. I have reenabled it. I had deactivated the plugin but have turned it back on now. The settings turned on are:
– Cache hits to website for quick access
– Use PHP
– Compress pages
– 304 not modified browser caching
– Cache rebuild – serve supercache file to anon
– cache timeout 1800
-Timer 3600 seconds
– CDN off
– preload cache files every 100 mins
– preload all posts
– preload mode
– debugging enabled
Cache tester – timestamps match.
thanks for your help!
