Are you sure you want to ….? problems.

Hi there.

All of a sudden I seem not to be able to edit posts or settings anymore in my wordpress. When editing posts I get the response: “Are you sure you want to edit this post?. If I click “Yes”, the post isn’t changed. Also, some characters like “ó”, are displayed incorrectly, and the visual rich editor is lost? When I try to edit a settingspage, I get the question if I’m sure if I want to edit the settings? Then right after that it shows the “All options” page ??? How can this be? Please help! Thanks!

Regards,
Dennis
