When entering invalid export image settings, no usefull error message is produced:
1. Settings (note the resolution which is not within the acceptable range):
2. Error message:
This is extremely unfortunate, as i had unintentionally changed this setting and spent hours with the support team trying to find the issue. I think it would be very easy for the dev. team to implement an error message if invalid settings are set. We were on a wild goose chase, resetting lightroom, creating new profiles, using a different windows account, until the idea struck us that maybe it was just wrong settings all allong...
Easy fix that could save the Adobe Team huge amounts of time troubleshooting such issues!
