Ok, The site is working fine but I've installed a new module and I'm receiving this error when trying to access the admin login now. I cannot login to the admin. I am a beginner level coder.

> 
> Notice: Undefined property: Loader::$load in /hermes/walnaweb03a/b905/moo.mattestincom/peddlerplace/osclass/shop/vqmod/vqcache/vq2-admin\_view\_template\_common\_header.tpl on line 96
>  Fatal error: Call to a member function model() on a non-object in /hermes/walnaweb03a/b905/moo.mattestincom/peddlerplace/osclass/shop/vqmod/vqcache/vq2-admin\_view\_template\_common\_header.tpl on line 96

I was able to find this file (admin\_view\_template\_common\_header.tpl) in my FTP. I opened it in Sublime Text Editor and line 96 shows this code

```
<?php $this->load->model('multiseller/upgrade'); ?>

```

Below is the full code of the entire admin\_view\_template\_common\_header.tpl file

[Error: undefined property $load](https://stackoverflow.com/questions/16841915/error-undefined-property-load)
Take me to what I believe may be very similar.

If this is the case, How do I find

```
function __construct()
{
    parent::__construct();
    /*Additional code which you want to run automatically in every function       call */
}

```

\*\*\*\*\*\*\*\*UPDATE\*\*\*\*\*\*\*\*
After following the suggestion and changing the code, this error now appears
