Installing and upgrading help

Here is my setuplib.php file starting on line 522, and bold italicized is line 541:

$suffix = '';
if (phpunit_util::is_in_isolated_process()) {
$suffix = '.isolated';
}
test_lock::acquire('phpunit', $suffix);
$dbhash = null;
try {
if ($dbhash = $DB->get_field('config', 'value', array('name'=>'phpunittest'))) {
// reset DB tables
phpunit_util::reset_database();
}
} catch (Exception $e) {
if ($dbhash) {

$DB->set_field('config', 'value', 'na', array('name'=>'phpunittest'));
}
}
unset($dbhash);
}

Just to clarify a typo, I said "Here is my setuplib.php file starting on line 522, " but it is actually my /lib/setup.php file.

Here is my full .htaccess file:
RewriteEngine on

I checked my server and have multiple .htaccess files currently (/moodledata and /public_html). Did you need to add it to a specific folder or did it need any specific contents?
