The SSL certificate for printerpotty.com was recently renewed but the process for installing the certificate had changed without anyone realising, so from 24th to 30th December, most browsers were displaying a warning that the site was insecure, etc…
Just to reassure anyone who might have been concerned, the site was not hacked or exploited, it was a basic setting error that should have been spotted and fixed.
The new SSL cert has now been installed, and the site should no longer be displaying any errors.
