However, this used to work fine on portal 2.6.0.DR1. Since I switched the portal version, I can see the login page, but after hitting the login button, I'm presented with this exception. I suspect it is related to the fact that our portal is heavily hacked into, in order to change the default theme, but I'm not sure... Any ideas/hints/pointers/anything?
