twentysixteen child theme – (index) css overrides style.css

Hi,

I’m trying to create a bespoke site using a twentysixteen child theme, but the font-family css is being overridden by css at ref. (index):nn – in this case, ‘font-family: undefined,sans-serif!important;’. If I uncheck this the formatting returns as it should be.

I have no idea what is going on. Can anyone help?

You can see this at http://www.theparentsunion.uk – inspect element on the article title on the index page, for example.

Thanks in advance,

Tim
