White Screen of Death after saving settings. I Fix it, please read!

Hi,

I have a Multisite install. I starting getting a white screen of death after saving anything, a post, settings, activating/deactivating anything.

The WP_Debug gave me the following error, coming from your plugin:
http://codex.wordpress.org/FAQ_Troubleshooting#How_do_I_solve_the_Headers_already_sent_warning_problem.3F

As it turned out, your admin.php had a few lines after the last closing ?> tag. Deleting these lines and spaces fixed the issue.

If you would be so kind to do this simple fix for next version so the plugin does not break again the WP installation.

Thanks!
