Sorry to post another thread here but it is the only way I can be sure people read this.The Annexe was put on a new server on Sunday and this change involved a DNS change (mapping jonbanjo.com to an actual IP address).
A number of browsers, even when set to check new pages every time are exhibiting weird caching behavour and picking up pages from the new server as well as (in some cases now non-existant pages) pages on the old server as well as errors caused by the old pages being found.
As far as I can make out, everything is OK on the new server and the DNS changes have gone through but it will probably be necessary to clear your browsers cache before the site operates correctly.
