I'm using version 2.6.10, and using custom filters for various listing types (Acreage, Waterfront, Commercial, etc.) and the filter returns the same results - all listings (I only have 2 currently).
I did need to modify define.php to make the widget search work correctly (tested, and working).
The site is http://dev.wilddesign.biz/whitemarshProperties/ The custom filters are used on each of the options under "Find a Property".
Does anyone have any suggestions? PLEASE HELP!
