I'm moving to a new host soon so will be having to rebuild my vps server. I currently use the dot deb repository and have the option of using 5.3 or 5.4 but I'm not sure which to go for. Has anyone any suggestions on which would be best? I only use xenforo and wordpress on the server. Will I have any problems that anyone is aware of? and does anyone know if APC cache works with php 5.4?
