Hi,
i bought your extension about a month ago and it works fine, but now it stop showing the extra field group associated with the category.
I install an other extension for filter item, maybe they are in conflict?
Update:
my site is in Joomla 3.6.5 and K2 2.7.1.
I try in an other site with K2 2.6.9 and it works fine, after i update K2 to the latest version and it still working, so i think there is a problem with an other extension
