A website I have used regularly for 10 years has had a makeover, and I can no longer access it. The log-in is a pop-up and my computer freezes. It belongs to a well-known publishing company and a sister website has had a similar makeover; I can access that site but only using Opera. Edge, Safari, Chrome, and Firefox will not let me log-on. i have tried on 3 different devices, one an android, and on a brand new computer that had never ever logged onto the internet before I tried to access that website. All devices run different security suites, and the 2 Windows computers are absolutely up-to-date running Windows 10. For months, the response I get is the standard clear your cache etc, done long ago and repeated regularly, and didn't apply to the brand new Windows computer. Chrome is the only browser to suggest that the security certificate has problems, all other browsers, including Opera, freeze. The message I get from Chrome is:
"Your connection is not private" or "NET::ERR_CERT_AUTHORITY_INVALID" or "ERR_CERT_COMMON_NAME_INVALID" or "NET::ERR_CERT_WEAK_SIGNATURE_ALGORITHM" or "SSL certificate error"
I'm not sure their customer relations person is even reading my responses! I have phoned them, pricey from Australia to the US, and emailed many times asking to be put in contact with an IT tech who knows what they are talking about, no luck! I would not normally worry, and simply write the company website off, but it holds 220 downloads of mine, and I need to check I have a back-up copy of each one. My problems started with the update to Win10 Creator's Edition that co-incided with a major Malwarebytes update and a major Firefox update, back in May. I am guessing that the problem is something in Win10 Creator's Edition doesn't like the log-in procedure and somehow it upsets a Microsoft security setting, but I am having the same problems using Android now. Any ideas?
