Error in website

First off, try to deleting foobox-image-lightbox plugin.

Access your server via SFTP or FTP, or a file manager in your hosting account’s control panel (consult your hosting provider’s documentation for specifics on these), navigate to /wp-content/wp-plugins/ and delete this foobox-image-lightbox plugin.

Thanks for the reply sir,
i have deleted the “foobox-image-lightbox” but still getting errors. ??

By the way, please check your wp-config.php and check if you see this line in there:
define('WP_DEBUG', true);

If you do, change it to:
define('WP_DEBUG', false);

thanks again
