In magento enterprise version. 1.14.1.0 ,I want to sort manually the categories order (categories - manage categories), when the page is ready, I do drag and drop with the category but after ajax saved if i refresh the page the order is not working properly, I look around but i don't have find nothing. I try also, tried to re index data but nothing change, why don't work?
Use f12/right click inspect console and reload the category page. Check to see if you have javascript errors as the drag and drop functionality uses Prototype heavily.
You likely have some output in your index.php or javascript clash.
Finally success,there was not any error in magento coding level.Actually we were importing category via csv file,there was a field name 'position' ,we have fill this field with sorting numbers according to category position.
Cheers.
