Admin CP left nav frame blank

[Sidane]

Have been experiencing at odd problem with my vBulletin's admincp which has only started in the last few hours.

When I log into the CP, the left frame where the navigation links are displayed is completely blank, except for the vbulletin logo image at the top.

See screenshot.

As far as I know, nothing has been changed on the server itself and I don't know of any setting in vBulletin that could have accidently made this happen.

Obviously this is a bit of an inconvenience so any help would be appreciated.

Turns out PHP was upgraded to 4.4.2 on the server a few hours ago. Could this be the cause of the problem? If so would anybody now what setting in PHP could be causing this.

Oddly enough the left nav bar in the Mod CP works fine....

Problem solved. The new version of PHP was compiled without XML support which prevented the navbar links from being created.
