WordPress in 000Webhost

Hey, I have completed the ”5 minute install” guide and when I go to the ”wp-admin/install.php” I get the following error:

Fatal error: Call to undefined function stripslashes_deep() in /home/a9679802/public_html/wp-settings.php on line 502

Does anyone know how can I fix this?

Thanks!
