theme translations.
There are no issues using a WordPress multisite installation or translating the theme into other languages, however to clarify, ClassiPress is not multi-language capable by default which means although you can translate the theme into any language using the .po language files, there is no automatic language selector allowing multiple languages for one installation. This is where multisite would be useful, as you can have a separate installation for each language. Thanks.
