I migrate a site collection from version 2010 to the 2013.
I have a list with a custom content type. (document set).
When I try to open a document with the url
I get the error
File Not Found
I checked the log and the error is on this file
ToolBar.ascx exists in the hive
I tried to remove the import of that page from the
docsethomepage.aspx page of the content type (
_cts/myContentType/docsethomepage.aspx) but it is still not working.
I tread to delete the page
_cts/myContentType/docsethomepage.aspx but I still get the same error, so I guess I am editing the wrong page.
