Thanks for the awesome plugin! We're using a lot here in my office.
So, the problem is that I have two sites, in the same host, with the same 3.6 version of wordpress, the same theme (pk sold!) and the same version of woocommerce (2.0.13).
I'm having problems to calculate the shipping with Correios in one of them. It's http://www.laborconcursos.com.br. Ojn the checkout page, when you try to calculate the shipping, a unrecognized character appears in the state field and the log says:
09-12-2013 @ 17:33:10 - Weight and cubage of the order: Array
[weight] => 2
[height] => 10.2
[width] => 10.2

09-12-2013 @ 17:33:10 - Requesting the Correios WebServices...

But, on my other website, http://www.mourasuplementos.com.br, it's ok.
This error was happening on mourasuplementos too, But was fixed when I restore a version of PagSeguro's plugin. I tried it in laborconcursos too, but it was unsuccessful. What should I do?
