Yeah i can
If they worked previously, and you can run them manually, it sounds like a hosting issue, possibly.

Try it and see if it works then. Good luck to you.
You can generate a timestamp for how long a user will be in jail (time()+60*60 = 1 hour ahead in the future), for example and then check whether time() has exceeded the timestamp and if so, they aren't in jail anymore. That principle is not only resource friendly, but it saves the headache of cronjob's not working. In some things, you might need a cron job but reducing the dependency on them will make things a lot easier.
Just another dude.
This Thread helped me fix my cron problem thanks guys
braidz your problem might be your hosting might not allow cron jobs , maybe change host , if your hosting is free , go premium?
