Fatal Error

Fatal error: Class ‘pagination’ not found in /home/content/p3pnexwpnas02_data01/35/2078335/html/wp-content/plugins/email-suscripcion/emailing-lista.php on line 502

When I click on the “E-mail List” to check my subscribers I get the above error message and I do not get the list of subscribers. How can I get this fixed and how can I recover my subscriber roster?
