If you tried to view the site this morning (Sunday, 10th July) and got a weird bunch of nonsense instead then please accept my sincere apologies- as you can see, things are up and running as normal again.
I was updating the system I use for administering the site and the auto updater failed, resulting in the error messages. It then took me 3 hours to discover which file was not playing properly. I got there in the end so all is well.
Many thanks for trying again.
