Website problems

[Anonymous]

Each time I go to the O2 website I get.....

There is a problem with this website's security certificate.
	The security certificate presented by this website was issued for a different website's address. Security certificate problems may indicate an attempt to fool you or intercept any data you send to the server.
	We recommend that you close this webpage and do not continue to this website.
	Click here to close this webpage.
	Continue to this website (not recommended).
	More information If you arrived at this page by clicking a link, check the website address in the address bar to be sure that it is the address you were expecting. When going to a website with an address such as https://example.com, try adding the 'www' to the address, https://www.example.com. If you choose to ignore this error and continue, do not enter private information into the website. For more information, see "Certificate Errors" in Internet Explorer Help. Any ideas?

I've just tried with IE and I'm not getting that, it comes up as a secure site.

Norton Safeweb finds nothing wrong either:
