custom header on single product page

Hey guys,

i’m not sure why but a cant seem to change the header of my product pages.

for all the other pages i’ve been using the

if(is_page(page_id_here)){
get_header(‘header’);
}
else if()…. etc.

but i cant get the product page header to change. what am i missing?

i’ve checked the single_product.php and some other .php files corresponding to the product pages. But none of them effect the header. i’m geussing i’m looking in the wrong places. but i have no clue where to look.

second thing is that i have te same problem with this text “Gecategoriseerd in :

Dit bericht is geschreven door Mitchel A”

this is dutch for: categorized in : , and this message has been written by Mitchel A

i have no idea how to get rid of these things.

hopefully i’m clear enough!

kind regards,
Mitchel Abrahams
