I've inherited a Drupal website and all seems fine.
I can login to the admin user and administer everything I want to. No problems.
My customer, using the same URL, with the same admin user credentials can see some parts of the Drupal admin system, but others keep on asking him to re-enter the username and password.
This happens on the Drupal Admin Dashboard and Content pages.
Client just gets a popup dialog asking for the admin username and password.
We renter the correct details and the dialog just keeps on popping up.
Can anyone help us to determine what is different on my clients computer / browser from that of ours?
We've tried in Firefox / Internet Explorer and Chrome.
Is this IP address related ?
Only difference we can see is that he is on Windows XP whilst we are on Windows 7 - surely that cannot make a difference?
