    When attempting activate the plugin, wordpress throws and error saying that the headers are not valid.

    You could open up the plugin's file(s) and make sure there are no blank spaces before the first <?php and the last ?>. That often does the trick.

    Clicknathan, you are right. All you have to do if you get "The plugin does not have a valid header" error is to edit one file - wp-content/plugins/collapsing-links/defaults.php. In line 19 you have to remove the blank space before ?>, save the file and you are done.

    I still get: "The plugin does not have a valid header."
