InDesign CC 2015.3
OS X El Capitan 10.11.3
InDesign won't export project to PDF press quality, or predefinied. As soon, as it starts exporting, it gives a short error "PDF cannot be exported." I tried removing some of the linked PSD images, and only then the export could be done without error.
Any help much appreciated.
It helped. I changed linked PSD images to tiff files. Thanks!
