please check admin->event viewer to see the "real" issue (the exception you see if simply ajax saying a server request had an unexpected exception)

that exception occurs when you have a site that has requestValidationMode="4.0" set on the httpRuntime node in web.config. This is incorrect, as it needs to be requestValidationMode="2.0" -if you change it that will likely fix your error. Note: during install/upgrade we detect .net 4.0 and adjust this value as needed, I recommend you check and make sure that web.config is not read-only (and that the user your application pool is running under has read/write/modify permissions) as it may be that this value could not be updated by DNN due to insufficient permissions
