[TYPO3-english] Words missing after update

[Jeppe Donslund]

Hi

I just update a TYPO3 installation from 4.5.11 to 4.5.39.
But know a lot of words are missing in the backend.

In the pagetree titles with danish letters are missing.
If I wanne edit a page and click the icon nest to the page title, the options number 3 (Edit) and number 5 is missing the words.

I have compared the database
I have deleted temp-files

What else should I do?
