Search function not working in all browsers

Hi Xanu,

I have this shortcode on my page, [pdb_list target_instance=1 search=”true” orderby=”first_name, state” order=”asc, asc,”]
and it seems to work fine for me in Safari & Firefox (Mac). Not working in Chrome(Mac) and Firefox (Windows) and I think a few others. Disabled all other plugins, cleared cache (Disabled caching for now), even just used the search shortcode, still the same. Could you guess what I am missing? Thanks in advance.
