dbconnect.php is a completely different file. Here's what it should look like:
PHP Code:
<?php
define("EZSQL_DB_USER", "root");
define("EZSQL_DB_PASSWORD", "root");
define("EZSQL_DB_NAME", "pligg");
define("EZSQL_DB_HOST", "localhost");
function _($s) {return $s;}
?>
You can either enter in the vallues manually and comment out the second to last line: // function _($s) {return $s;}
If you do a fresh install leave the file as is and upload it to your /libs/ directory.
