I think nobody else has faced this problem, and it's a very big problem for me since I need to translate the jquery datepicker in different languages.
It's doing the translations fine when going to /en/ or /fr/, but for some reason php can't seem to detect the variable $_GET['glang'] well to detect in which language it's displaying the page. Whenever I echo it it comes blank.
Any alternatives? It's currently working under Wordpress 3.9.1. Is there any other variable to see? Thank you!
