For quick fix:
please go to ow_plugins/articles/views/controllers then open view_index.html
then replace the whole line 38 by
{add_content key='socialsharing.get_sharing_buttons' title=$info.dto->title description=$info.dto->article entityType='articles' entityId=$info.dto->id image=$info.dto->getThumbnail()}
Then set OW_DEV_MODE to true, f5 site, back to false to clear html cached files.
P/s: We will apply this fix for next release.
