Official Advice for anyone having problems accessing the site

[mdingwall]

Hi Mark Dingwall,
We purchased a new SSL certificate however if there are still issues for users this most likely will be because browsers and devices will cache SSL status

please instruct users to

Clear their cache and Site settings and data - they should not need to clear their history but those settings are usually accessible when you look and click on the settings to clear browsing history for a particular site.
you can refer them to this link

Thanks. Worked for me, although still saying it is unsecure but can get in.
