 * I have developed a plugin which used to run without any problem until the released
   of version 3.0.
    When i try to activate the plugin this message is displayed 
   by the wordpress.
 * “The plugin generated 560 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.”
    Can anyone explain
   to me what could be the possible reason behind this.It runs fine in version 2.9.2
   but 3.0 gives this error.
