what to do when my dnn site shows "Object reference not set to an instance of an object." error?
There could be many different reasons for this error. The most common cause is the application tries to do some initialization from files such as database, xml, text files etc. Usually there are diagnostic messages follow after the error message above, such as sql error if it is database related. Usually it is caused by missing configuration files. Please double check if there are config files that have not yet been uploaded to the site folder.
