Problem with "Grant needed permissions now" - post to fb page

Hi there,

When I am logged in to fb, when i click on "Grant extended permissions" in the main control panel, nothing happens. When I click on "Grant needed permissions now" from the post page, the post editing page just gets refreshed.

When I am not logged, clicking on either of the above just asks me to log in (new window appears), and after that noth happens.

I can see the list of pages i can put the post to from the post editing page. Just cant get the permissions thing to work. When i just try to force the post to the page, the error message appears saying the post was published but not to the fb page.

Thought it's smth to do with my computer cache, but after clearing it, same thing happens.
