For testing purposes, I use Opera browser, and I never store any data in there. I do not have a single cookie or file stored, is 100% empty. So, to test your shop, I came here and did copy paste in Opera, with english as one of my prefered languages and your site appeared in english. Went there now to see it again and was in english. The only way it does not show in english is when I delete that language from my browser preferences. In conclusion, the problem is in your browser, not you site. If you had an alternative browser set to english as default lang. and without Duch in it, of course, maybe it would help you see. Now, Very Important Thing: it seems that /webshop is a redirect, "www.lxdrums.eu" is the main page, so, this is most probably what is causing you this problem; you have to put the tag in this first page also, because this is the main page of your domain (I'm gessing this file must be in the filesystem root: "Index.php". As this first page doesn't have the tag, even I can't see it in english.
