Hi,
Yes the problem should be fixed already. Have you deleted all the URLs with wrong language? Is this one newly generated?

Hi
Yes, I deleted all the bad urls, cleaned the cache just in case and activated the source tracing. In a few hours the bad urls started to appear again. The last trace is from these last urls...

We'll make some more tests and try to solve the problem definitely.

After installing the latest version I've noticed that I'm getting a lot of URLs without the language code (I got some before, but now the problem seems to me greater, or that is my impression). All the options in the language tab are set to yes, including 'Always use language?'

For example, events/xcentric-scenes-in-the-life-of-mary-shelley instead of en/events/xcentric-scenes-in-the-life-of-mary-shelley . The real URL doesn't have a language parameter ('index.php?option=com_k2&id=1951&view=item'). Notice: I'm also getting the URLs with the language parameter and the site seems to work ok. It may be a problem with robots again...

After the update to v.4.4 everything seems to work fine so far... :-)
