category filters have disappeared

Hi, 

I have recently had to start to look at making the change from Adirondack 7.0 to Brine 7.0 with the view of upgrading to 7.1 from there due to hitting the limit on 200 products. 

I have successfully moved over to Brine but for some reason the category filter in my shop has disappeared, i have googled and searched everywhere but i cannot seem to find the answer, does anyone have any suggestions? Since the shop has quite a wide variety of products this really needed. 

I have seen somewhere that there is a toggle switch to turn it on but i do not seem to have it or have just missed it. 

Any help much appreciated. 

Kind regards

Henry

Thank you, you have just solved the one headache i have had over Christmas! 

Happy new year!

Kind regards
