Exclude Pages Widget or code

I wanna hide a page in my navigation menu.

I have installed the exclude page widget .. but it doesnt have any effekt on my side even though I take the x aways and update and all.

So I have been looking for the code wp_list_pages(). I wanna hide the page ID 1577 .. so wp_list_pages(‘exclude=1577’)

But I have been looking and searching in my theme SimpleScheme Magazine…. And can’t find it..

So now I dont know what to do. Do you have any good ideas.

By the way I have problems when I wanna link, or put in images .. I always do that manual.. I don’t know if theses things could be connected.

Best regards
Henrik
