I have a problem that daily snapshots only run once. It

Hi!
I have a problem that daily snapshots only run once.
It seems that anything I schedule in the cron to run regularly only runs once (or never) and the next schedule never gets updated.

Any idea where that could be from?
Works fine on my localhost installation and I only get the issue on my live server...

Anyone experienced that and has clues on how to fix it?
I'm planning on reinstalling wordpress on the server to see if it changes anything but it feels like it might have to do with the server configuration itself and there I'm totally lost!
