Faster Web Site?

I’ve made some changes which should speed up how quickly pages load on the web site*.  As far as I can see everything still works but if you have found something that does not work please email me!

Thanks!  Peter Taylor (site admin: info@srcmbc.org.uk)

*for the computer geeks I’m using php 7.0 (rather than 5.5) and “W3 Total Cache” which is a WordPress plugin.
