If anyone has php accelerator running on their servers make sure you disable it BEFORE installing 3.5.X branch.
It's caused alot of grief for many people. Turn php accelerator off install the new version, finish designing it and then you can turn it back on otherwise you'll have random cache problems and corrupted displays from the word go.
3.5.X branch seems to suffer from this more than the older versions it's certainly something that changed in smarty.
If anyone knows the correct settings for php accelrator so we can avoid this please let us know! The default settings can play havoc with x-cart and x-affiliate.
Server and apache resets can cure some problems but they resurface again later
