Hi Chris,
You are correct, I can confirm this is an issue. It passed the test, as there was a different solution in effect on our test servers, and it went unnoticed.
For temporary fix, you will have to replace one file in the plugin directory. Let me know if you need help with this.
– Open up the wp-content/plugins/ajax-search-pro/includes/classes/search/class-asp-search-terms.php file on your server
– Replace it’s contents with this
– Save it, and the issue is fixed
This should fix the problem.
