Humm, yeah, there is no much we can do with that version. It is no longer supported.
That version didn't have localization for the datatable. In fact that version renders the table in plain html by default The problem is something else.
What I would do is to enable the developer console in the browser and see if there is any javascript error showing up there. Also, enable the developer logs in Moodle, and also to check the logs in your webserver. There must be an error message somewhere. The blank page is not giving really any clue on what could be wrong.
