Shew!!! Got very frustrated. did complete installation again new database new dotnetnuke. But this time with the template files in place with the config files all correct. I can see from the database that my pages exist only I can't get the page to dispaly. The installation was not successful I got this error -

From what I can gather this is an asp.net permissions problem - but I have all the permissions set same as before. Do I give up or is there a solution?

• which DNN version do you use
• does both portals (export and import) have the same modules and module versions installed?
• be cautions with modules, that have multiple module definitions like blog. There is a known issue, that will be fixed in next DNN version
• please be aware, that only modules supporting iPortable interface are included in templates.
