I thought I had all the issue on generating output solved. But this morning when I click the Generate icon, I have no choices, previously had (Responsive, PDF, etc).
Now there are none and the Generate Button is disabled.
Did a setting get changed?
You are saying that there are no presets showing, correct?
If so, I haven't seen or heard of that occurring so no known tricks. If
closing and reopening the project doesn't fix it, I think it is a case of
creating new ones.
Here is what I see when I try to Generate.
Look top left and click the Output mode. Then look at Output Presets.
