Error when using checkboxes to filter

  • 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.
