We have a particularly annoying problem at our school when our students attempt to access a Moodle web site using Internet Explorer 7, 8 or 9 on WinXP and Win 7 computers.
Students are able to access the Moodle web site OK and obtain the login screen. However when they enter their username and password and click the Login button their login details are wiped out and they are returned to the login screen minus the login details that they entered. On some occasions they are able to login OK but this seems to be a random occurrence.
However when using Firefox they are able to login to the Moodle web site without any problems. (Unfortunately we cannot use Firefox at our school because our IT Manager has a policy of using Microsoft Products)
We have tried clearing the Internet Explorer cache of Browsing History and Cookies prior to login but to no avail. The login problem is still there. Can anyone help because I am starting to run out of ideas.
