Thank you for your post.
Something has changed in your environment.
I doubt the fms14_settings.settings file has been deleted, so this issue may be memory related or the Admin Console and FileMaker Server may be out of sync. Therefore, close all hosted files, stop FileMaker Server, and reboot the server to clear out any possible memory conflicts. Once the server reboots and FileMaker Server restarts, launch Admin Console to put it back in sync, and then see if the schedules appear and/or if you are able to save a schedule.
Keep me posted with any progress.
Thanks, Gal. I did restart the adminserver, but that by itself didn't help. I'll try a restart this weekend and let you know.
