I got this error after successfully uploading files of a new plugin into my root folder but I have no idea what caused it.
Notice: Undefined index: token in /home/turb9452/public_html/vqmod/vqcache/vq2-admin_controller_common_header.php on line 5
the bolded below is line 5
<?php
class ControllerCommonHeader extends Controller {
public function index() {
$data['d_shopunity'] = $this->url->link('d_shopunity/extension', 'token='.$this->request->get['token'], 'SSL');
$data['title'] = $this->document->getTitle();
if ($this->request->server['HTTPS']) {
$data['base'] = HTTPS_SERVER;
} else {
$data['base'] = HTTP_SERVER;
}
any idea on how to fix the error?
