Certificate error: navigation block - Facebook Social Network

Please tell us your operating system (Windows 7, Windows 8, Mac OS X 10.8, 10.9 etc.)

In general, certificates will fail if your computers clock/date/time is incorrect. Check your settings and try again if necessary.

Is the time and date correct on your computer? These certificates are dated and if your computer is out of that date range, you will get a certificate error.

Go to to Tools->Internet Options->Advanced and uncheck "Check for server certificate revocation"

facebook security certificate

You should be able to either navigate the site anyway, or permanently disable the warning.

If you would like to permanently disable the warning:

Click Tools and select Internet Options
Click the Advanced tab
Scroll down and ncheck "Warn about certificate address mismatch"

Hi, please check if the date and time of your computer is correct, if not then correct it then close and reopen your internet explorer. let me know if that works.

fix time and date ...it might not be ok ..and it sees that the certificate you are running it not in use until some time after ...and this might cause it ...if it is not this ...uninstall the explorer 7 ...it will roll back automatically on explorer 6 ...and all will be ok ...
so go to ..c panel ...add/remove programs....click on explorer and click remove ...follow the instructions...if you really want it ...you can reinstall it from the net ...and any errors will be gone..

Click on Accept Certificate.

Then Install Certificate.

Then Accept Security Risk.

I will work.

Thanks.

Mr. Vidya the problem mentioned by you can be solved by resetting your browser. To reset the internet explorer follow these steps:

2> select run
3>In the run box type -> inetcpl.cpl
4>You will get the internet properties window
5> select programmes tab and click on reset
6>select advanced tab and click on restore defaults
