Authenticate invalid certificate in IE


I use Twitter web authentication for signing in to a website and it works fine except when I tested it at an Internet café the browser blocked the authenticate page (… ) with a message that the certificate was invalid or something like that and when clicking to remove the block manually the Twitter sign in page was displayed without CSS styling. I couldn’t find out what version of the browser was but it was some fairly recent version of Internet Explorer.


Correction: It may have been an older version of IE such as version 7 since a Google +1 button I added recently didn’t show up on the webpages in that browser version.
