Open_basedir php warning

We noticed following error in our error log on the host.

PHP Warning: file_exists(): open_basedir restriction in effect. File(/public_html/wp-content/uploads/sucuri) is not within the allowed path(s): (/tmp/:/var/tmp/:/usr/local/php70/lib/:/usr/local/php54/lib/:/usr/local/php55/lib/:/usr/local/php56/lib/:/usr/local/php70/lib/:/usr/local/lib/php/) in /public_html/wp-content/plugins/sucuri-scanner/sucuri.php on line 7854

What can we do about this?
Thanks!
