Error home redirection and links

hi, first of all thanks for the pluguin is the first time I use so I’m not sure if I have to change some settings, I have placed on this site palorosa.mx the problem is that the default language should be Spanish but when I enter to the home ir send me to English, if Im in this language no problem but in Spanish there are times when the menu links send me to their versions in English and also in the home I have placed 3 links at the bottom to the different sections using the code documentation:

href = "<? php_e("<!--:es-->http://www.palorosa.mx/contacto<!--:--><!--:en-->http://www.palorosa.mx/en/contacto<!--:-->"); ?> '

But there are also times fails and sends me to the versions in English.

P.D. sorry for my bad english 😛
