okay my friend...
i was curious about this issue so i tested a translation in the "Feedback" module. again, compare the code:
GOODdefine('fb_frontend_comment_header', '<a href="mailto:%s">%s</a> wrote at %s:');
define('fb_frontend_header', 'We would like to hear your opinion.');
BADdefine('fb_frontend_comment_header', '<a href = '\"mailto:%s\">%s</a> written at %s:\\');
';
define('fb_frontend_header', 'We would like to hear your opinion.');
you can see how this is all jacked up. perhaps the translation module tries to do addslashes() or some magic_quotes crap.
Perhaps the best option is to edit these translation files manually. just go to:
/modules/feedback/languages and you'll see it. i didn't notice anyone else with these issues while i was browsing the original thread for the "languageedit" module. so, who knows.
again, i hope this helps
