wordpress 3.1 problem with category searches

I too had the same error when linking on categories from languages other than default. my site is http://dentaldicroce.com. multilingual content is powered by wpml.
however this plugin didn’t quite resolve the problem for me… now i keep getting double language directory:
even if the href is written as http://dentaldicroce.com/en/categoria/smiles-gallery the browser opens http://dentaldicroce.com/en/en/categoria/smiles-gallery and redirects to homepage.
Could there be some sort of solution for this as well?

sorry, i didn’t understand your comment 🙂

This plugin has partially solved my problem.
Now there is no warning: reset() [function.reset]: Passed variable is not an array or object in …/query.php on line 2890

But when opening the category archive page the language directory is doubled: /en/ becomes /en/en/ and so the page is redirected to homepage.
While empty categories are being redirected to original site content (default language – which is ok.)

For example: http://dentaldicroce.com/en/, in the left sidebar “advanced technologies” menu there is a category link to “diode laser” (this category is not empty and is supposed to open an archive page with one post). instead it is redirecting to homepage with the following address: http://dentaldicroce.com/en/en/categoria/advanced_technologies/diode_laser

any ideas?

Resolved by downgrading to 3.0.5 and am perfectly happy now!
Only that now i have to repost all the posts that i’ve made after the upgrade 🙂 good to have backups 🙂
