My site is safe!:
It no longer has a certificate, but this is because my host, TSO Host, is under administration and now want me to pay £60 per year for a certificate. For both of my sites that would be £120, which I refuse to pay.
TSO Host is eventually being taken over by 123 Reg, but in the meantime I remain uncertificated while I look for alternative hosting packages.
Desktop has been ignored:
I have been concentrating on the mobile version of the site & I've been ignoring the desktop version. I have now noticed that many of the pages don't look right on desktop... I will be correcting this asap.
