 * hello, i have several errors with the plugin. i have installed contact form 7
   and the sending is done via postman. if i send a test email it works fine, but
   in the form it doesn’t work, also i have many errors in the server logs:
 * Got error ‘PHP message: PHP Warning: Trying to access array offset on false in/
   var/www/vhosts/xxxxxxx/httpdocs/wp-content/plugins/postman-smtp/Postman/PostmanOAuthToken.
