Hi all,

I'm getting the below error message in 3 separate testing environments all using umbraco 4.5.1:

1. Windows 7 32bit, iis 7, sql 2008 express, fresh install - after clicking "Create" and choosing a node in Media and Content

2. Windows small business server 2003, iis 6, sql server 2008 express, existing site - after clicking "Create" and choosing a node in the Media section only (Version = 1df4af7c-48f7-4060-a407-8e882b999c8b)

3. Live web server - unknown specs but running windows, asp.net 2+, sql server 2005 + - after clicking "Create" and choosing a node in the Media section only (Version = unknown as it is a remote copy therefore no error messages available)

Server Error in '/' Application.

On all testing environments we can create new media items by right clicking on a mode and clicking create.

There are a few other threads about similar errors I have found on google but no solutions within them have worked - one included running a SQL script to look for "ghost" nodes but that yielded no results.

Can anybody shed some light?

Thanks very much in advance!

Max.
