When working with the REST Controller in FuelPHP and accessing it from your browser you see “Arr” when a format is not specified in the URL instead of the expected data in your default format. This is because of a setting in the rest.php config file (fuel/core/config/rest.php OR /fuel/app/config/rest.php).
<pre>’ignore_http_accept’ => false,</pre>
<pre>’ignore_http_accept’ => true,</pre>
This is faster and will make your default the default format as expected. If the client needs the data in another format they can specify it in the URL.
