Logging in to giffgaff.com... .

I have an unusual problem which I can't seem to solve. I can't log into giffgaff from this particular computer. My login details are correct because it works with another computer on the same wireless network. I have tried deleting cookies, have used Chrome, IE and Firefox, and all that comes up is 'unable to login - wrong credentials'. I can log into other websites so I would assume it is not a problem with accepting cookies.

When I try to log in through Chrome I get a warning at the top with a red cross through the lock icon. It says the following:-

"The identity of the website has been verified.

My connection to the website is secured with 128bit encryption, however the website includes other resources which are not secure. These can be viewed by others while in transit and can be potentially modified by them.

The connection is encrypted using RC4_128, with MD5 for message authentication and RSA as the key exchange mechanism. The encryption is not compressed. The server does not support the TLS renegotiation extension."

I don't understand a word of this, am not sure why Chrome doesn't warn me of it on other computers and don't know how to resolve the problem... . I have run Malwarebytes and Windows One Care and have a firewall and anti-virus running so the computer is virus-free (I think)... .

    This is a bit of a wild guess but: are you fully up to date with Windows Updates?

    The symptoms might be explained if one or more of the trusted root digital certificates have expired on that PC - IIRC there was an update recently that installed new ones.

    It works! It's actually my mum's PC which I had setup to automatically update Windows. It seems that it hadn't been doing it for some reason but now I've updated it, giffgaff works. Many thanks :)

    I spoke too soon... . It seems to work intermittently now. The Chrome message in my OP hasn't returned but it does fail to log in more times than not, giffgaff telling me: 'unable to login - wrong credentials'... . Everything up to date now and still no viruses... . Any ideas...?
