After a move to a new Webhost my Joomla 1.5 installation does not allow me to login the admin panel any more. Altough Login data is correct it always redirects to the default login data. Shared Host, only ftp and phpmyadmin access available to fix this, no changes to the server or [url removed, login to view] possible. Easy job for someone who knows the problem.
Need it done asap.
