Import language pack in 1.4 from 1.3

[sannie]

Hi,

 

I'm trying to upgrade my Prestashop 1.3.6.0 installation to 1.4 and am encountering problems. One being updating the language translations..

 

In my current PS 1.3.6 I have made a lot of changes to the nl and en language for a customized theme. In the backoffice administrator panel of 1.3.6. I've exported these languages to nl.gzip and en.gzip. When I try to import these packages in PS 1.4.4, Tab Tools-Translations, I keep getting the error Archive cannot be extracted.

 

Has somebody seen the same problem and/or know how to solve this?

 

Many thanks!
