metatags don't change

Dear zencarters,

When I change the metatags in the catalog admin, they don't change on my website.
I replaced several metatags.php with the originals, without result.

Does anyone have suggestions?

kwekerijdonker<dot>nl/bamboe

I see this on home page
<meta name="description" content="Voor een niet woekerende bamboe, kom je naar kwekerij Donker toe." />

and this on a product page
<meta name="description" content="Fargesia Angustissima is a non-invasive bamboo. " />

Thank you for looking. I forgot to select product name: yes, and product title yes, at the metatags page.
