Menu "Graph Trees" does not work

[gemini40]

Hello!
There was a problem that the menu "Graph Trees" content is not displayed(

We have a lot of graphics, but they are not visible (
The file tree.php in the directory is.
What could be the problem?

Cacti Version: 0.8.8a
OS: FreeBSD 7.2-RELEASE-p2

Thank you in advance!

Try to check permissions.

Вы бы систему обновили уже.

Ok, I'll try this.
I also add that we have two trees. One by default (and with it everything is all right), and our second one. The only problem is with them.
