Dear Colin,

I think that it is as simple as the security settings of the browsers and what they warn about. With 'Warn when using a fradulent website' (desktop) or 'Fradulent Website Warning' (phone) active, expired certificates are sufficient to flag it.

I think that Dave has updated the certificate now as I did not get the warning this morning.

Best wishes and happy wargaming/modelling/collecting (delete those that do not apply :)),
James

Thank you, I used to be a Wargamer but now more of a collector.
As a side note, it’s amazing and awesome how Dave has kept PSR up and going all these years and always updates the latest sets. A truly valuable resource for 1/72 figure collectors.
