The lang attribute in the HTML says which language a page is in. On this page it does not match the language in the address, for example lang="nl" on a page under /en/.
Screen readers pronounce the text in the wrong language, browsers offer the wrong translation, and search engines get a mixed signal about who the page is for.
Snaglist compares the lang attribute of every indexable page with the language code at the start of its address and lists the pages where they differ.
