When I login as a site manager and perform a simple keyword search , things are fine; I get the instant result listed (fig-1, see attachment.jpg) and then the faceted-search result with the filters (fig-2).
However, if I login as a site collaborator, with the same keyword, I can get the instant result (fig-3) but the faceted search result does not appear, I get a blank page (fig-4).
I have customized the edit properties forms and advanced search form to include the categories field. Is the above problem a 5.0.a bug or due to improper customization or else?
Please help, thanks.
