The Q-and-A plugin puts a “Continue reading” link at places where it should not be active in the first place. I’ve tested it: The “Continue reading” on this page http://dev.smmp-online.org/angebote/zu-gast-im-kloster/ is positively rendered by the Q-and-A plugin. Some function there is going wild. Also, submissions.php is not answering to the language file. Only hard coding can change the $message there.
