I have a Twitter train script installed on my website, but it won't work properly. After making a payment, visitors do see the message that their VIP account will be added - but the account is never actually upgraded. (Don't know what could be causing this - maybe a script error, maybe something simple like a wrong cron job...???) I can't get any help from the person I purchased it from, so I need someone who is prepared to take a look to find out what's wrong...
