Check that the language definition you've edited doesn't break with 'or ". The definition looks like this:
define("_MOD_DEFINITION","Translation"); or
define('_MOD_DEFINITION','Translation');
if you add ' or " in the text, you break the define(), and therefore screws up your page. You can use \' (I think), or use 'within " encapsulated defines (like define("_EXAMPLE","That's an example");, but NOT like define('_EXAMPLE','That's not the way to do this'); ) As you can see in the last example, it'll break the define right after That, because it ends the define with 's.
Hope this helps
