I have built up a site in 4.2.4 and it is using English and Spanish. However the supplied Spanish language in the software is horribly inaccurate. The grammar is all over the place.
My client who is also Spanish has updated his languages on the old site (in 2.2.5)
Is it possible to export the language variable file from 2.2.5 and import that into the new site in 4.2.4?
It would make my client very happy!
