Fatal Error on V2 Listing Pages

Hi there, here’s what I get on my staging site when I click on any GD listings page. All other pages are fine including the details pages and all the add ons/plugins are V2 up to date. I’ve tried disabling all the plugins as usual but still the same result. Is it that the 1280 theme is not compatible with V2 generally? All other themes work but I don’t want to have to change to a different theme and have to restyle everything. Thanks in advance, I’ll pass on log in details in the next post.
