cakephp: php version problem (i think) need help

so, i was building this website using cakePHP 1.2.1.8004 on my local and it was pre-developed until i got my hands on it, and yesterday i finally uploaded it so that it could go live, but apparently there's a lot of functions that were undefined and make my web goes all "white screen of death"

on my local i was using xampp 1.7.1 with php 5.2.9, and my online server is using php 5.2.17. i am thinking like the problems were coming from the php version difference, and i am trying to replicate it on my local by finding a xampp version which has the same php version, but apparently xampp doesn't have any bundle which includes php 5.2.17. now is there anyone who has had the same problem like i do, and confirm that the php version is really the source of the problem here so that i could reinstall the php on my server and do开发者_如何学JAVAwngraded it to pp 5.2.9? or should i look for another solution ?

thanks

This sounds suspiciously like a server rewrite issue. I would verify the URL rewrite is working correctly. Also, do you have debug turned on in core? It may shed some light on the issue as well.
