Okay so I found the file is in “images/warptheme” and is called “header_bg.jpg” – I replaced that file and it’s loading the new one.
I found on the page code that this file is referenced in a DIV with the class “sp-page-title”. Found that class in many files but I assume the one I need to edit (if I want to edit it) is in “templates/wt_grandy_pro/css/template.css”
Is that correct? I just want to make it a tiny bit shorter.
