When i upgraded my install to version 5 I have the following in the upgrade log

System.Data.SqlClient.SqlException: Violation of UNIQUE KEY constraint 'IX_DNN_ModuleControls'. Cannot insert duplicate key in object 'dbo.DNN_ModuleControls'.

Error: Cannot insert duplicate key row in object 'dbo.DNN_PortalLanguages' with unique index 'IX_DNN_PortalLanguages'.
The statement has been terminated.

While the site has installed the English lanuge Australia this does not appear as a choice in portal site settings - or under user options.

I am also a little confused about the tabs that should appear under Admin. There are no icons for either Admin or Host. The Language tab appears as a page and opens a mudule but has nothing in it.

I have removed the portal alias error from site page by removing the module from the page. I understand this is the work around.

I am unable to export a template with or without content.

Thanks

Paul
