I have narrowed the offending file down: config.dpu.php (admin/includes/autoloaders)

looks like it is missing "?>" at the end of the below code. Anyone else see any problems?

<?php
// Dynamic Price Updater 5.0


if (!defined('IS_ADMIN_FLAG')) {
die('Illegal Access');
}


if (IS_ADMIN_FLAG === true) {
$autoLoadConfig[999][] = array(
'autoType' => 'init_script',
'loadFile' => 'init_dpu_config.php'
);
} else {
trigger_error(__FILE__ . ' loaded from catalog side, verify upload of files.', E_USER_WARNING);
@unlink(__FILE__);
}


// uncomment the following line to perform a uninstall
// $uninstall = 'uninstall';

Remember that since the log was issued from the admin, its contents will include reference to your admin directory's name. Be sure and xxx those occurrences out and post a pertinent log within a "CODE" tag (the big # in the menu bar shown when you're writing your response).

You should have a log file for the spinner. Check for that.

AND, a new fix for the spinner. fingers crossed
