Can't see workflow settings in Drupal content type edition

Someone gave me a drupal site made with drupal 6.19 in order to add the i18n module. I'm trying to follow the instructions listed here:

I have already installed and enabled the i18n module however, 开发者_如何学GoI have an issue with this part:

Go to Administer > Content Management > Content types > Pages > Edit. Go to the bottom of the page. You'll find a section called "workflow settings". Open it and activate Multilingual Support.

I can't find the workflow settings anywhere, I checked the source code of the page and I saw that the section is hidden with display:none but I don't know why... I checked and re-checked the admin user permissions but I don't have a clue, I haven't worked with drupal in my life either. Can somebody help me?

Thanks a lot.

From my comment: Try switching to Garland (or any core theme that you know hasn't been tampered with) to see if you can see everything and do what you need to do, because it seems that someone decided to hide those settings through CSS in your current theme.
