CRON Problem

[Bag72]

Using Docker on QNAP NAS. Set up and started system. Logged in changed password.

Went to General section typed in */15 * * * * in CRON field. Hit save and it responded with a 'Cron expression is not valid'.

Nobody else is reporting any errors so I suspect that I am doing something stupid and not discovered a bug that has been dormant for some time as Cron is so heavily used.

Any ideas?

Went back and after playing for a while decided to wipe it and restart. Do deleted all files and directories. Creating dirs and files from scratch.

Worked fine this time so I must have corrupted something somewhere when I started setting it up.

Sorry for wasting your time. Please ignore me as I slip back into obscurity. :)
