 * Hi,
    When activating the plugin I got this error:
 * Cannot send session cache limiter – headers already sent (output started at /

   wp-admin/includes/misc.php on line 1116
    Skip to main content Skip to toolbar
 * The plugin generated 2 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.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fplugin-error-109%2F%3Foutput_format%3Dmd&locale=en_US)
