Link to test case: Internal system so I can't really give you a usable link.

===========================================

Debugger code (debug.datatables.net): I got a 403 error when I hit the button so I pasted it here below.

===========================================

Error messages shown: No errors are shown - simply the tables rows are not displayed as if there are no rows (the data source has data).

===========================================

Description of problem: From some reason I fail to add another column.
I currently have 7 columns and I wish to add another one, but once I do it fails to display the data.
In the code pasted below you can see a column is commented - as long as it is commented the data is displayed.
Once I uncomment the column no data is being displayed and I get a message of no data to display.

I know it is a weird issue but I really hope you have an idea on this.

Upload configuration data
Upload your table's configuration and data to allow for further analysis.
It can often greatly assist in debugging a table if we can see the configuration and data in the table. This feature of the debugger will read your local DataTables configuration and upload it to debug.datatables.net for inspection.

Important: The data uploaded to the server can only be viewed by SpryMedia employees will be automatically deleted after two weeks. The data will never be sold or otherwise published. It is used for debugging any issues you are experiencing with DataTables only.
