For my PhD thesis, I'm using the following template available at: https://github.com/mcmanigle/OxThesis
When I compile this in TeXStudio with pdfLaTeX everything works well. However, when I use LuaLaTeX - which I prefer, especially in order to avoid issues with special characters - I get a range of "! Undefined control sequence." errors.
Unfortunately, my knowledge of TeX is much too basic to figure out what I should change in order to make this template work with LuaLaTeX.
Any help / suggestions would be very much appreciated!
