How to fix certificate error in Internet Explorer 8?
I just fixed my laptop, and I found that many of the sites that I always visit have certificate errors and the security certificate is expired or not yet valid, etc... Why did this happen? Is there anyway I can fix this problem? Thanks.
The main reasons for Internet Explorer certificate errors are:
• The date of your computer has been set to a wrong value
• The Security Certificate has expired
• The website is actually unreliable
The common explaination could be the computer's wrong date. Because the security certificate is valid for a period of time. So if the time is incorrectly set on your computer, you may receive this security certificate error message when browsing sites. So the first thing you are supposed to do is to check the date on your computer. Usually, after setting the date correctly, you can access the sites normally. If not, the security certificate of the website may really have expired or the website is not trustable. So never put your important password or login ID on such page on which Security certificate error happens.
