Thanks, that worked!!
I have a last question: in my homepage, I can choose between two languages: Spanish and English. When English is selected, if I want to come back and start reading in Spanish, the link created is: http://clinicaciro.es/en/es/inicio/
In these two cases, the link configured in the theme is "/en/inicio/" or "/es/inicio/". So, how can I force the page to reload in Spanish when I'm reading in English?
Hope I explained my problem so you can help me. Thanks a lot
