My localhost installation of DNN was running blameless. After I oppened the application with VWD it runs under http://localhost:49299/dnn/ but not under http://localhost/dnn/ any more.

Hier it jumps to: http://localhost/dnn/Install/UnderConstruction.htm and I get the error message:

This site is currently unavailable
Please check later

I don't know why it happens, and am not sure if this compiled installation will run later on the production server?

I need to compile this application because of some newly added external controls.

Thanks for your hints

 

 

Are you running in VWD or back to IIS when this happens?

I run in VWD and it works!

After that once I run it in IIS (http://localhost/...) it doesn't work.

Thanks

Check the PortalAlias table in your database, and make sure that it points at localhost.
