I have been using a transparency flattener preset for a long time that is set to outline all fonts. I'm not sure when it started happening, but now it fails to outline the fonts — even in a document with a single text box and nothing else. Is this a bug?
I'm using InDesign CC 2015.2 on Mac OS 10.10.5.
Is there an object on the page which has 0% Transparency, 0% fill? If not, put one on the page.
Thank you, that was it. I guess I forgot you need to include a transparent object.
