"I've also got it on xampp" isn't a check at all, unless you're running XAMPP on a Celeron 400 with 96MB of RAM and a 5400RPM hard drive on a remote machine you're accessing via TokenRing. You have no latency, multiple channels, local resources that would cost you hundreds per month in a datacentre, free access to features and settings that would be freakishly dangerous on a shared hosting server, etc. You asked for help, and you're refusing to give anyone the information that would allow them to give you the help.
