Virtuemart 2.0.22b - Link with SEF

Virtuemart 2.0.22b - Link with SEF

I work in a new project with VM 2.0.22b, with two languages (EN and PT),
but I have a problem with SEF.
The problem is, I have the website with PT language as default, and EN is
secundary. When I enter in the website in PT, I navigate without any
problem, the links are correct, goes to the correct menu ("Loja online" in
PT), the products well to. So, I change the language to EN, the problem
begins. The links in VM are all wrong, show me something like
"http://www.site.com/en/component/virtuemart/CATEGORY/PRODUCT?Itemid=283".
In PT this don't happen.
If I disable the SEF, everthing works fine, and both languages.
I need fix this, someone can help me? Thank you.
