php error in plugin admin

Hello,

I see This message only, when I open plugin page in admin

Fatal error: Cannot redeclare stripslashes_deep() (previously declared in /home/XXXX/public_html/v/wp-includes/formatting.php:2027) in /home/XXXX/public_html/v/wp-content/plugins/tubentertain/tubentertain.php on line 299

Can you help ?

Thanks
