Hi to all first, and thanx for this wonderfull code. Guys I have a little problem. I use version "Ultimate_SEO_URLsv21da" witch runs very good. Whats my problem? Well... We all have'it. My site has now 5 lenguage and supose I am reading spanish, and just whant to switch to english, the content of the page will switch BUT THE URL ADRESS ( the product name ) will still be in spanish ( not english). BUT IF I click another time on the english flag - only then will change the URL - with the product name in english. Why ? And How we can corect this small flaw? My main problem is becose I whant a perfect XML sitemap. To do that I use xml-sitemap contribution. And this contribution will navigate and will make an index of strange pages like: product name in spanish and the content in english :((( And of course the sitemap will be segnificantly bigger! :(( This problem it's for the experts, I can not figure out this... sorry guys.. I count on you! Thanx all! My site it's here.
