Unidentified index, variable, and permission denied

Question

I am using opencart 2.0 and everything works fine until I installed an extension. I already have a theme previously installed but after inserting the extension several errors appeared. I am not familiar with Php so I am having a hard time figuring things out.

I did some research and some says it may be a version defect but everything I used are precisely for opencart 2.0, the other one says that it may be that the config file was not set properly,but I didn't move my site from local to live yet so everything in my config file are all correct. And he last one is to insert isset, I am not sure about this but from the looks of the code I think everything was set properly.

This are the errors

And this are the codes

d_quickcheckout.php on line 644

return $this->load->view($template, $data);

payment_address.tpl line 85,86,87,and 88

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']; ?>]['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']; ?>';

vq2-system_engine_loader.php on line 37

require(VQMod::modCheck($file));

When I checked my vqmod log this appears

Answer 1

There is a typo in the code d_quickcheckout.php in line 641 this causes line 644 to look for a variable that has not been set.

Change $templatetemplate to $template in line 641.
