cron permission denied

[DSD]

I've been fighting with the crontab editor (build 6.0) and I see that it's been fixed in the newer build of cpanel, but I haven't upgraded yet.

Anyway, I keep getting these errors emailed to me:

/bin/sh: /home/account/public_html/.sql/backup.php: Permission denied



but when I run it from my browser, the script emails me my backup (executes and does what it is supposed to).

Does anyone know why this is happening?

Thanks
