[TYPO3] Ajax don't working on backend!

[Unai Aizpurua]

Hi all,

I have an instalation of typo3 updated from 3.7 to 4.0 correctly.
But the ajax in the backend don't work, for example:
· When you click over the icon of a file, it have no menu,
· Can't move the pages
· Everything that depends of contextual menus doesn't work.

I have updated to typo3 4.1.2 and the menus doesn't work.


The debugger tells errors on

file:alt_db_navdframe.php

xmldoc has no properties
var t3ajax = xmldoc.getElementsByTagName("t3ajax")[0]; line 106


What can I do? Someone has seen something like that?
Is very important to have it runing.


Thanks in advance.
