Hi, I got an problem when I tried to move my DNN site to other server. I've installed DNN on server A successfully, and the database is on server A1, but they are all testing enviroment, so now is the time to publish it on the production server, I copied all the source file to server B, and copy the database to server B1, change the web.config file's connectionstring, and when I try to link to the site, it shows up like this, could anybody help? Really appreciate it.
