I have enabled "cookies from everywhere". In the browser cookies list there are lots of cookies from many pages but not mine.
I´ve just made a test with index.php, idex-es.php, and only one sub-page in each language and don´t give me any error, but always start in catalan
(I´m doing it all in my localhost. I have the web in the net in just one language yet, www.ktrens.com
I would like to solve the language issue before uploading all.)
