I just updated my site from 2.5.14 to 2.5.19 and Datatables no longer works. I even removed version 1.13.17 and upgraded to your version 1.13.22 to see if it fixed the problem.
It works if connecting to the Joomla Database, but it does not work when connecting to an external database.
Even debug mode shows nothing. It just says "No Data Available"
I know it's something connected to the 2.5.19 update because I have another component ArtioFusion Charts that has also stopped working. It no longer shows external data.
Please help! I have over 300 tables using your module for an online sales newsletter. Right now it is showing nothing on my updated site...
