Can anyone advise on how to implement a (temporary) Url to access an upgraded DNN installation formatted like:

[serveripaddress]/[subdir]/[subdir]

E.g.: 66.67.122.123/text-text-text/text.com/ ..default.aspx

Installation: DNN 5 version upgraded to DNN9
Working ok locally, now moved to server. Keepalive.aspx page reached ok, but cannot reach DNN installation.

Several Portalalias versions added to table. Tried using web.config hostheader (to remove subdir in url) but doesnt work either.

Note: no defaultportalalias in the portalsettings table (not added during upgrade). Could this cause it?

Any suggestions most welcome. Thanks.
