When a site has been saved as template and then automatically uploaded and activated in the solution gallery and a user is trying to create a new site based on this custom template he get's an error saying:
"A duplicate field name was found."
The template site and the new site that should be created are located in the same site collection. I've found that 2 tasks list exist with the same column name.
What can i do on the site that the custom template was based on inorder to get the custom template to work? Can i import the wsp to visual studio and change any xml? What xml should i change? Can i delete the list on the template site that contains the field name and recreate the list? Can i rename
Ofcourse there is the option of recreating the template site from scratch, but i do hope it will not be necessery.
