Diagnosis.
CHECK THE PATH
The most common cause. A wrong or relative path means nothing runs.
Use absolute paths, starting from your home directory.
CHECK THE INTERPRETER
The PHP binary path must be correct.
If your account uses multiple PHP versions, the default may not be the right one.
CHECK THE SCHEDULE
An incorrectly entered schedule may mean the job runs at a time you did not expect, or never.
CHECK FOR OUTPUT
Set the email field temporarily. If the job runs, you receive something, including errors.
Silence means it is not running at all.
CHECK THE SCRIPT WORKS
If you can run it another way, do.
A broken script fails whether cron calls it or not.
CHECK THE ACCOUNT
A suspended account does not run cron jobs.
CHECK THE ERROR LOG
Errors from cron-run scripts appear there.
IF NONE OF THAT HELPS
Open a ticket with the exact command you entered.
