Freepbx has crashed, can't apply changes


I have freebxp 2.1.1 and centos 4.3. Everything was working fine. I wake up this morning, I can’t open extentions link to add some extentions anymore. When I make changes to anything within the interface; like trunks change, there is a red bar on the top that suggest to click on it so the changes are saved, after I click on it, my browser just spinning and does not save the changes; the red bar still there. How can I solve this issue?. I already reboot my system twice. I have installed trixbox 1.1 and all the update available. Please help

Thank you
