 * Hi there, when I enable mail poet and a add-on for contact from 7 my theme breaks
   and I get this error in the debug log:
 * [23-May-2018 00:36:53 UTC] PHP Notice: Use of undefined constant MP_SEGMENTS_TABLE–
   assumed ‘MP_SEGMENTS_TABLE’ in /home2/samp/public_html/wp-content/plugins/mailpoet/
   vendor/j4mie/paris/paris.php on line 215
    [23-May-2018 00:36:53 UTC] PHP Fatal
   error: Class ‘PDO’ not found in /home2/samp/public_html/wp-content/plugins/mailpoet/
   vendor/j4mie/idiorm/idiorm.php on line 320
 * Any idea what is going on there?
 * Thanks,
