Empty Edit page when locale is enabled

Hello,

Hope somebody can help me.
After an update, when i enable the locale module when i try to edit a page i just get a blank page.
Disabeling it i can again see the content.

Creating a new page, whatever content i add to it, remains blank.

I have tried to change the languages that are enabled and what is set to default but nothing seem to help.

I am quite new to drupal and would appreciate any advice.

Thanks

Rene Castberg
