We just installed WP Ultimate search on one of our sites, then we purchased the Pro version and successfully installed the license key. The Taxonomy tab is now enabled.
The Category and Tags taxonomies are selected by default. I can see the Format taxonomy also, as well as my own taxonomies (there are 6).
Problem is that I cannot save any settings on that page. I cannot disable either Category or Tags taxonomies - even after unchecking them and saving settings - they are still checked/enabled.
Same goes for my 6 taxonomies. I can enable them by ticking them, but even after saving settings they are no longer ticked.
I can't enable or disable any of the taxonomies. Has anyone had this problem?
