I succeeded in installing and using Gtranslate PRO version.
The problem is that when in the sentence there is a ' or a ", no matter what, it will add a backslash to the sentence \
Like in this page:http://www.cuoremediterraneo.com/en/surf/
where the sentence
Many names for just one unique and wild area: the "isola dei gabbiani"
Many names for just one unique and wild area: the \"isola dei gabbiani\"
and the sentence
These dunes hosted Paolo Silvestri's school
These dunes hosted Paolo Silvestri\'s school
what can I do to solve this problem?
This happen with all languages, not just english.
