I am not able to open the Magento Connect Manager.
The backend is working fine, but after the login to access the Magento Connect panel I get redirected to this url showing me a blank page:
My server is running openSuse 11.4, my Magento version is 1.8.1.0.
I have also tried to run the Magento clean up tool but nothing changed.
