 * Was just testing this plugin. First WordPress showed an error during plugin activation
 * > The plugin generated 3 characters of unexpected output during activation. If
   > you notice “headers already sent” messages, problems with syndication feeds
   > or other issues, try deactivating or removing this plugin.
 *  and then when I tried to edit a post I saw Warning: Cannot modify header information–
   headers already sent by (output started at /home/user/testsite/wp-content/plugins/
   webtimer-plw/webtimer-plw.php:1) in /home/user/testsite/wp-admin/post.php on 
   line 235
 * This looks like a nice plugin and would love to get it to work. Thanks
