php script not running

so i have the code below, for some reason the require_once(‘connect.php’); works but the require_once(‘config.php’); doesn’t work. i then tried moving the code fomr config to connect.php but that also didn’t work. i feel like it because of define(“name”,“value”); is messing it up. any ideas?
btw mysql_connect(“dbname”,“user”,“pass”) works if i type it in directly.
and the file manager for interworx is really bad. What do you guys use? for php/htm editing

<html>

<style type="text/css">
    .fieldset-auto-width {
         display: inline-block;
    }
</style>

<?php
echo "support php?";
?>

        // connecting to mysql
      
        $result = mysql_connect(DB_NAME,DB_USER, DB_PASS);
        if (!$result) {

        }
         echo  "Connected successfully to MySQL";
        // selecting database
        $selected =  mysql_select_db("studymob_dbTest");
         if(!$selected)
             echo "Can't Select Database";
         echo "Connected Successfully to database";
        // return database handler
