Presta 1.5.2.0 - Currencies are not refreshing when changing laguage

[satania]

Hi, I have a strange problem. I have 2 lang versions in my shop - Polish and English. For polish currency is PLN and for English version EUR. Sometimes(not every time let's say 1 per 3 times) when I change lang versions(from EN to PL), the currency is not changing I mean:

-page lang is changing and I see text in Polish

-every rule for Polish version is working(e.g. if value of cart is higher than 500 PLN shipping is free)

But the problem is that my currency is still Euro - everything is in Polish, but for example I have 10 euro instead of 40 PLN. Do you have any suggestions how to solve it, 'cause it is quite problematic for me?

 

Presta 1.5.2, Ajax cart in use

 

I am using Block lang and Currencies and Languages by prestahelp.com

 

It seems that's the problem of Ajax, 'cause when page fully reloads currency is chaning, but when it's not fully refreshing currency is not getting changed.

I found the solution on forum so you can mark it as solved. I will put it here so other people will not strugle with that case. I am not author of code.

 

This works for 1.5.2 for sure. Just remove [THIS LINE ADDED] [/THIS LINE ADDED] and [THIS SECTION ADDED][/THIS SECTION ADDED]
