Language change error

[arnpro]

Hello everyone, thanks for reading.

 

Recently I was testing my site when suddenly, nooooooooooooooooooo what the hell happened in here?, I tried changing languages, while viewing a product, and it threw me an error, an URL like this:

 

h ttp://localhost/catalog/product_reviews.php?products_id=2&language=es&osCsid=074a3cc58fce370f38b95d1c04057521

 

h ttp://localhost/catalog/product_info.php?products_id=19&language=en&osCsid=074a3cc58fce370f38b95d1c04057521

 

And the browser printed something like: This page is not redirecting properly

 

Notice in what pages they give me the error.

 

This doesn't happens if I go to h ttp://localhost/catalog/advanced_search.php, I try to change the language there and it works. EDIT: pages tested working: shopping_cart.php, login.php, account.php (can't stand trying for more ;P)

 

There must be more pages where it gives me error but I really don't want to keep looking cause it'll keep briging me down!:( (everything was going fine)

 

Please help out, and thanks once again.

 

EDIT: it does change the language, because when I press back button, I go back to last page with the language I selected.

Can anyone help me out?
