    Removed Feature with Update? So great folks, you invalidated the key and my website served up an http 500 error. First I had to track down what was happening in the errorlog because I couldn’t even log in to the dashboard. And than I had to remove your autoload file manually via FTP. That’s how you think to make friends?

    Hey Montegrifo, sorry to hear about the 500.

    Did you contact our support team?

    Let us know!



    Well, no because for each try to access the website I got one of these:

    08.01.2018 08:53:34 … PHP Fatal error: require_once(): Failed opening required ‘/mnt/web011/e2/59/56953559/htdocs/WordPress_SecureMode_01/wp-content/plugins/mailpoet/vendor/composer/autoload_real.php’ (include_path=’.:/opt/RZphp56/includes’) in /mnt/web011/e2/59/56953559/htdocs/WordPress_SecureMode_01/wp-content/plugins/mailpoet/vendor/autoload.php on line 5

    And after I removed the autoload file it was gone. What else is there to do?

    It looks like some plugin files are not being installed properly.

    You could try to re-install it manually by following these steps:

    1. Login to server using FTP, and navigate to /wp-content/plugins/ folder.

    2. Delete all MailPoet plugin folders

    3. Download MailPoet plugin from

    4. Extract the plugin from zip and upload the folder to /wp-content/plugins/ directory

    5. Once MailPoet plugin is uploaded, go to your WordPress dashboard > Plugins > Installed plugins and activate it.

    Please, let us know if this helps.
