Hi Daiana,
It probably depends the Social plugin you use.
On my own website, i use Social-Media-Feather, and, even this plugin is not multilingual it’s possible to translate some features, for example its tooltips.
Check this out: https://bleublancrousse.fr/lesfiertes/
For that, i created an wpml-config.xml in /wp-content/plugins/social-media-feather :
<wpml-config>
<admin-texts>
<key name='synved_social_settings'>
<key name="share_message_default" />
<key name="facebook_share_title" />
<key name="facebook_follow_title" />
<key name="twitter_share_title" />
<key name="twitter_follow_title" />
<key name="google_plus_share_title" />
<key name="google_plus_follow_title" />
<key name="reddit_share_title" />
<key name="pinterest_share_title" />
<key name="pinterest_follow_title" />
<key name="linkedin_share_title" />
<key name="linkedin_follow_title" />
<key name="tumblr_share_title" />
<key name="tumblr_follow_title" />
<key name="mail_share_title" />
<key name="mail_follow_title" />
<key name="rss_follow_title" />
<key name="youtube_follow_title" />
<key name="vimeo_follow_title" />
<key name="instagram_follow_title" />
<key name="flickr_follow_title" />
<key name="foursquare_follow_title" />
</key>
</admin-texts>
</wpml-config>
In this file, i can add lines, such as <key name=”facebook_follow_link” />, in order to be able to have a specific facebook url by language.
Christophe.
