I need help locating the view I need to modify on the page. www.givemeachancefoundation.org/advertising-opportunities
I want to modify the table that is being used to display. I need to make layout responsive by replacing the table with Rocketheme Gantry responsive grid as RT does not support the bootstrap responsive built in.
Can someone help me locate which view I can edit?
I have tried all layout sin category view bu that table seems to be missing in the DIV layout so it must be calling i from another piece of php

Hello,
Can you tell me what do you exactly want to edit on that page so that I can tell you which view's file to edit ?
Thanks
