At last it seems I can use K9 again. I downloaded the beta version form the K9 site and all is well. This is the only version I can get working with ESS at the moment and is working very well. There are many parental filters out there, most want a yearly rip off subscription to keep it going. I have always found K9 to be the best one, and am happy again that ESS and K9 can work together again, I always lost internet access with the old version. It was a known bug. For info of those that had the same problems as me with K9.
