I too have this issue (WP 4.3, EM 5.6). Currently my work around is to update the event_status field in the wp_em_events table from NULL to 1. Any other advice on how to solve this would be great
I also noticed that the default value for ‘spaces’ changed from 99 to 10. I can’t seem to find where that is defined.
And while I’m asking: a setting to define a default start time would be nice too 🙂
Found it! it was the theme after all (only strange that changing themes didn’t make a change.
For those with the same issue: in the theme’s folder > file functions.php a bunch of ‘add_image_size()’ were added.
