I upgraded to 2.93 and I get the first error. So I checked the application pool and it was set to classic and the default website was set for default. I am able to login if I set them both the same either classic or default but they have to match. I am not sure if this changed with the upgrade because I did not change them and it worked fine before the upgrade. So I make them match and I can login again but every search is now broken. I recieve the second error below. I found a refernence to this error to enable buffering to true and that is already set to true. This is on 2008 R2 BTW.
