Hi Gary,

In Internet Explorer 9 and onwards you will sometimes see differing colours in the address bar, the differing colors mean:

Red : The certificate is out of date, invalid, or has an error.

Yellow: The authenticity of the certificate or certification authority that issued it can’t be verified. This might indicate a problem with the certification authority’s website.

White: The certificate has normal validation. This means that communication with the website is encrypted.

Green: The certificate uses extended validation. This means that communication between your browser and website is encrypted and that the certification authority has confirmed the website is owned or operated by a business that is legally organized under the jurisdiction shown in the certificate and on the Security Status bar.

A website's certificate provides identification of the web server. If the certificate has an error, it might indicate that your connection has been intercepted or that the web server is misrepresenting its identity. If you're absolutely positive of the website's identity, you know that your connection hasn't been compromised, and you understand the risks, you can choose to go to the website.

You can select Continue to this website (not recommended) on the certificate error warning page to go to the website. If you ignore the warning page and go to a site that's presented a certificate containing an error, Internet Explorer will remember the certificate while you have your browser open. You can return to the site without receiving another warning for that certificate until Internet Explorer is restarted.

Fixing the error

1. Make sure your computer's time and date are accurate.
2. Right click on the time to adjust the time and date.

If the error continues after trying the above steps:

1. Launch Internet Explorer on a desktop computer.
2. Click Tools | Internet Options.
3. - The "Internet Options" window appears.
4. Click the Advanced tab.
5. Under "Security", uncheck the boxes "Check for publisher's revocation" and "Check for server certificate revocation."
6. Click Apply.
7. Click OK. Close and relaunch Internet Explorer, which should correct the error.

I hope this helps in fixing the issue.

Regards,
Lokesh
