我正在使用opencart 2.0，一切正常，直到我安装了扩展程序。我已经安装了一个主题，但插入扩展后出现了几个错误。我不熟悉Php，所以我很难搞清楚事情。
我做了一些研究，有些人说它可能是版本缺陷，但我使用的所有内容都是针对opencart 2.0的，另一个则说可能是配置文件设置不正确，但我没有移动我的从本地到现场的网站，所以我的配置文件中的所有内容都是正确的。 他最后一个是插入isset，我不确定这个，但从代码的外观我认为一切都设置正确。
这是错误

这是代码
第644行d_quickcheckout.php
return $this->load->view($template, $data);
payment_address.tpl第85,86,87行和第88行
customer_group[<?php echo $customer_group['customer_group_id']; ?>]['company_id_display'] = '<?php echo $customer_group['company_id_display']; ?>';
customer_group[<?php echo $customer_group['customer_group_id']; ?>]['company_id_required'] = '<?php echo $customer_group['company_id_required']; ?>';
customer_group[<?php echo $customer_group['customer_group_id']; ?>]['tax_id_display'] = '<?php echo $customer_group['tax_id_display']; ?>';
customer_group[<?php echo $customer_group['customer_group_id']; ?>]['tax_id_required'] = '<?php echo $customer_group['tax_id_required']; ?>';第37行
vq2-system_engine_loader.php
require(VQMod::modCheck($file));
当我检查我的vqmod日志时，会出现

答案 0 :(得分：2)
第641行的代码d_quickcheckout.php中存在拼写错误，导致第644行查找尚未设置的变量。
在第641行将$ templatetemplate更改为$ template。
