Great Plugin... although I am having a small issue that should be easy to fix. Using the Query Multiple Taxonomies Widget with dropdowns, if i select "any" for all three categories the results are any post instead of any posts located in the given categories. This is what the query string looks like: "?grade=&content_area=&industry=" Becasue the values are null the results are incorrect. Anyone know of an easy way to fix this... or a hack where I can just place an if statment for three nulls and redirect to a specific url??
