Hi Peter
The culprit was the Smart Slider 3 plugin, upsetting the Google font attributes. It’s sort of fixed in the theme customisation of font weights now.
However I don’t like the weight of the font in the menu, it’s too “thick”. I have entered roboto as the font name but your plugin will not take the weight attribute after. I.e. roboto (300). It seems the menu font is somewhere about roboto (700).
How can I change the weight of the font?
Thanks
Steve
