 * Hi there,
 * Great plugin!
 * Today I tried to filter by checkboxes instead of dropdowns and got this message.
   I’ve deleted search form and started over, but still get this same message.
 * Warning: stripslashes() expects parameter 1 to be string, array given in /wp-
   content/plugins/ultimate-wp-query-search-filter/classes/uwpqsf-process-class.
   php on line 79
 * Any help would be greatly appreciated.
