Thank you for the suggestion Gido, but I’m giving up on this plugin, sorry. I’ve switched to WP Fastest Cache plugin, which is also free and it works great. All the problems I had with site security and Chrome rendering have been resolved – W3 Total Cache was the problem.
This hasn’t worked unfortunately. Any other ideas?
Thanks very much for the suggestion @gidomanders 🙂
I’ve changed the Cache Control Policy to that setting, will see if it works.
