I have a problem with a multi-lingual site and SEO Plugin
I set the languages en, de, it, and HTTP_Accetpt_language as default and checked Multi-lingual in Options/General
Then I enabled the SEO plugins seo_locale, dynamic-locale, sitemap-extenden.
With this configuration I got a multi-lingual sitemap (3 versions of each URI), but the flag switch does not work: when I use a English browser I get the English version of my site, but when I click on the Italian or German flag the site is reloaded, but it is still in English.
The same happen if I use an Italian or German browser: I get the site in the correct languages, but then I cannot change the language using the flags. The only way to switch the language is to add manually “?locale=it_IT” or “?locale=de_DE” to the URL.
Well, if I remove the dynamic-locale plugin, the flag selector disappear (and I could live with that), but the problem now is that I get a sitemap without the 3 languages.
Did I make anything wrong in the setting?
I tried all that with both official themes Basic and Zenpage.
