The webhost techno boffins sorted out the problems with my webiste. I wasn't even able to access the website emails for a while.
Hopefully, everything should be working normally. Those who have sent messages using the contact form on the contact page or direclty to the website email address will now start to receive replies. I'd like to thank Beatrice Thomas for dealing with most of the website matters; she will be doing so from now on in order to allow me to get on with other things.
