cant buy land, banker cant get money

Hi I have got the system working mostly but as the title of this post suggests, I cant buy or sell land, I get no errors on the console, just the screen panel saying cannot buy now, also the Banker cannot obtain money from the system, again I get no error on the console, just the screen floater says cannot get money at this time.
Thank you for your help
BTW I am running php 5.3.9 I just found something that 5.3.x doesnt work, should I uninstall and go back to 5.2.x ?
Thanks
