If your Squarespace template is displaying ‘read more’ in your article list it means it is pulling a snippet from your articles. If you do not write your own snippets, this will end up with problems since it will pull ….englis and then not finish the multilingual block.
The solution to this is to modify your articles and write your own excerpts which include the opening and closing 4 dots.
