change language in add listing pages

Hi all,

I have a problem with the add listing pages.

If I want to switch language in an add listing page from, for example, english to italian, I always redirect to the add listing page of gd_place

I’ll make an example:

I am on the page

http://museum-advisor.com/add-listing/?listing_type=gd_privateguides

And I want to switch language to italian. The right page that I should see after changing language is: http://museum-advisor.com/it/aggiungi-elemento/?listing_type=gd_privateguides

Instead, the site redirect me to the page
http://museum-advisor.com/it/aggiungi-elemento/?listing_type=gd_place

Thank you in advance for answering,

Gianluca
