Just launched a new site.
Client was reporting that he was unable to log in to admin area with the supplied username / password.
I verified that the account existed and that the client was in fact entering the correct details. Next I tried to log in from my own PC and it was fine.
The problem was that he would go to "sitename.com/admin" and after attempting to log in, the screen would go white, then he would be returned to the log in page. (But no error message)
I asked him to install the latest FireFox version and everything seemed ok.
However, we now have a problem: we created a staff extranet on the website. All the staff in the entire company are still on IE6 and they are unable to access the restricted pages (exact same problem as above).
I cannot ask him to upgrade all his staff PCs to IE7 / Firefox.
Can anyone help me troubleshoot this please?
