Hello,
Ticket #727989 (Create Date: 07/23/2016 4:58 pm)
and on wordpress.org forum post( https://wordpress.org/support/topic/364tags-and-categories-filters-dont-work-anymore/)
I have informed that from the version 3.6.4 the filter options stopped working. To this day the problem isn’t resolved no matter how many detail I provided on my ticket. I rolled back to the version 3.6.3 and filter options work fine.
I hope that this time someone answers and help me fix my issue.
