I have a fatal error on my site! cant do anything!

I have a fatal error and cant do anything! please can you have this removed somehow? If the wp smush pro needs to be deactivated and reactivated then that is fine. I need help asap! thanks

this is the message i am getting below:
Fatal error: Cannot redeclare i18n() (previously declared in /home4/shaneyam/public_html/wp-content/plugins/wp-smush-pro/wp-smush.php:275) in /home4/shaneyam/public_html/wp-content/plugins/wp-smushit/wp-smush.php on line 280
