Already solved.
The problem was that page theme is compatible with WPML and when detect new language activate its own switch, I have to modify the code of the theme.
Thank you and sorry for the inconvenience.
I’m sure it’s something very simple that I am missing, but there is no way to find it, someone comes up with anything that will try to solve it?
Ops, sorry. I start a thread now in that section.
How can I delete this thread?
Thank you very much.
