I think you misread, it's the text that's set to white, not the background.
I've tried removing headers, and headtags from the global options, it still retains to original photopost header. ie.
Code:
Content visible to verified customers only.
That's all I need to remove, and that's the header that's being generated by photopost itself, not anything I've added in myself. I can only assume it's generated by a template, or a physical file itself. I've just been unable to find it so I can remove it.
Sorry if I appear awkward, I very much appreciate both of your patience on this.
