 * Hi smiranda,
    I am sorry that this issue appeared for you.
 * We know what the problem is and we plan on releasing an update of WP Mailster
   that does this fix automatically, however this not ready yet.
    In the meantime
   we can fix this manually for you. However we need access to your MySQL database.
   Please contact us at [info@wpmailster.com](https://wordpress.org/support/topic/issue-with-database/info@wpmailster.com?output_format=md)
   directly so we can arrange this.
 * Thank you!
 * Regards,
    brandtoss
