Problem Adding Things to the Refine Search from form layout
I am trying to add different fields to the refine search and am editing my form layout. It won't let me check any of the check boxes for "Advanced Search". The only fields I can set yes for the advanced search are: Price, Country, Zip, and one of my custom fields that is a drop down. Everything else is greyed out and I can't check the check boxes. It won't even let me add the title to the "advanced search".
I am using classipress version 3.1.9. Help please!
