Solspace Tag "Suggestion" dropdown broken

Question

Using Solspace Tag 4.2.5 with EE 2.7.0

The suggestion tool is broken. Triple checked install. De-installed, reinstalled twice... /themes/ as well as /system/ files.

This is the error: http://cl.ly/U22k

Any ideas?

I'll post the answer here for more exposure:

There may be cases when the Tag custom field's autocomplete does not display any results.

First, please check if the domain in your browser address bar is the same as the domain set in EE. www and non-www domains are not considered the same. Domains need to be the same to prevent AJAX requests (used by Tag) from being considered as Cross-Site Scripting (XSS) attempts, which are blocked by browsers.

One solution is to set up config.php so that EE's site_url changes with the domain used in your browser. You can do this using PHP's $_SERVER variables. Here's an example. You would put this in config.php:

$protocol              = (isset($_SERVER["HTTPS"]) && $_SERVER["HTTPS"] == "on") ? "https://" : "http://";
$base_url              = $protocol . $_SERVER['HTTP_HOST'];
$config['base_url']    = $base_url . '/';
$config['site_url']    = $config['base_url'];
$config['cp_url']      = $config['base_url'] . $system_folder . "/index.php";

This assures that the EE domain for site_url is the same as my browser's domain, every time. This avoids Cross-Site Scripting issues when using AJAX.
