Cacti stopped working after PHP upgrade

[cbsys]

Hi,

Im running cacti 0.8.8a on a centos 5 system
Im using the atomic repo for PHP, as I need php 5.3 or above for other programs.
After running a yum update, my php has been upgraded from 5.3.3 to 5.4.17

Now I cannot get any cacti pages
I get the normal login screen ok
After logging in I get a blank screen!

Nothing is showing up in the http error log so Im not sure why

Any ideas?
Is there any other log I can look to for a hint?

Solved - it was the manage plugin causing my issue!
