I have a conflicting options error message, and I can't figure out what is causing it. Please see my set-up below. I realise this a pretty complex set-up, so I'm not looking for a full analysis of it; just hoping that someone might be able to spot something simple that I've missed, with just a quick read. Many thanks in advance.
The error message (the line number is sadly not helpful...):
example.tex:0 Conflicting options.
