I reviewed the posts on the forums but it is still unclear to me: we need to upgrade PHP from our current 5.1.6 to the latest stable, recommended version. Unless we get to 5.2.+ we are blocked from upgrading XOOPS, Word Press, Zen Cart etc. We run
CentOS5 Kernal and CPU: Linux 2.6.18-8.el5 on i686; Apache version 2.2.3
Do we need to upgrade the OS and or Apache before we upgrade PHP? and where exactly is this bleeding edge repository?
