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
mysite/listName/Forms/myContentType/docsethomepage.aspx?ID=1
I get the error
File Not Found
I checked the log and the error is on this file
mysite/_controltemplates/ToolBar.ascx
The file ToolBar.ascx
exists in the hive /15/ControlTemplates/
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.
UPDATE
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.
_cts/myContentType/docsethomepage.aspx
I do not see changes
