I have some basic open type (SC, Figs, etc) that work fine within FontLab. It compiles without error. It previews etc. When I go to generate an .OTF, it gives the following error:

ERROR: There was a problem while compiling OpenType font. Final .otf font is not saved. Please, check OpenType features definition for errors

Can anyone point me in a direction for this kind of error? How can I debug if the FL compiler isn’t showing errors? I know it’s hard without posting the font, but any ideas would be appreciated.

Thanks,
Randy
