Error when using certain options in the shortcode

Hello,

I tried to use the “Search and Filter” plugin on my local server and I received some errors when I used the following options in the shortcode:
– class
– empty_search_url
– all_items_labels

When I try to load the page I created using this shortcode with these options I receive the error: “Apache HTTP server has stopped working.” and the page won’t load.

I use the options like this:
class=”my-class-name”
empty_search_url=”localhost/mysitename/pagename”
all_items_labels=”,LabelA,LabelB,” (since I don’t need labels for the first and last fields)

Am I doing something wrong?
