Error Message

Fatal error : Uncaught mysqli_sql_exception: No such file or directory in /home/vol10_4/infinityfree.com/if0_35269947/nefanasa.free.nf/htdocs/index.php

Other Information

this is my code but never reach die(“ERROR”)
$conn = mysqli_connect($servername, $username, $password, $database) or die(“ERROR”);

i try browsing this error and many suggesting check mysqli is installed/corrupt or not.
