The 2 widgets created previously are now working, but I still cannot add a third. The theme is NOT responding in Widgets or in Theme Settings. I haven’t tried to make any other changes.

I can click on the link and get to the page, but it is then ‘locked out’ and won’t accept any mouse input. The Theme Setting Page shows tabs for General, Design, Slider, Custom Sidebars and Social Sharing, but has no context below them and are not able to be selected.

Please advise as the client has been waiting for a while to get the sliders and widgets updated.

Thanks,
Karen
