How did you make cron work in LibreELEC? I have enabled cron in kodi settings and set my system time and set a crontab to run, but nothing runs. My script runs manually, just cron won't do anything.
On a different note: where does cron put the mail notification in LibreELEC?
Sorry off topic, but nobody answers my thread asking the same question.
The reason for this is; I have a RPi 1B with only 1 core and webgrab takes more than an hour to run with no mdb job. I have installed the regular Linux WebGrab++ and want it to grab 2 days every day in the middle of the night.
I did have this add-on working, I just decided I needed more control.
Evidently, the MDB program got broken with a recent update, according to their forum.
