 * Hi
 * **When i activate your plugin this error massage appears:**
 * `The plugin generated 126619 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 plugin not activated.

 * Hi Frank,
    Did you upload the plugin using the FTP or by uploading it via the
   plugin browser?
 * is it a clean install? or do you have many other plugins and a comprehensive 
   theme installed?
 * Thanks,
    Daniel.

 * I would suspect this is the reason.
    For local installation you probably want
   to try and download the free 14 days trial [here](https://www.qm4.biz/cp_obs/order/index.php?task=product&product_id=25&category_id=1).(
   it doesn’t cost anything and no payment methods are needed.
 * But at least you will get to see it in full swing together with the Mailchimp
   integration and the PayPal integration (should you need them)
