Manager not showing document's tree

Hello there,
I have moved my site into a different server. It was all working perfect before, but now I have got a bit issue:

The site is up and running, but when I log into the manager, the document’s tree doesn’t show. I can see everything else on the manager but not the tree.

Any ideas of what could be happening please?

Details of my MODx installation are:
MODX 1.0.4 rev 6981
PHP Version 5.1.6
Mysql: 5.0.77


Thanks,

Hi,
When I’ve run into this, it has been that the server would only show the tree if I used "www" in the URL. In those cases I’ve either forced the whole site to use "www", or in some cases just the manager, using .htaccess. If that’s not it, smarter server minds than I might know.

Good show listing your system info, btw.

Cheers, Dave

thanks Dave!! Unfortunately that didn’t fix it , but thanks anyway,

Any more ideas anybody?

It happens in every browser?
Try to clear MODx cache and browser cache.

yes, on every browser, if I look at the code, the tree is just not on the frame. The tree is not there at all. Anybody any ideas??
