The web hosting Tentmaker has been using moved us to new servers; but in the process did not move our SSL certificate and changed a number of other settings required for the site. We were not adequately informed of this in advance and so could not take steps to prevent problems.
I have now moved the tentmaker site to new hosting.
I apologise for the inconvenience to customers.
If you have made orders in the last two weeks, I advise contacting Phil directly on +44 1782 746879
