Hi there,

I am not sure how I can add lines to the header when I am using the Renew Child theme. Is there an easy way to do this?

Thank you

Hey there,

Thanks for writing in! For this particular situation one of the easiest things you could do is output some content via a custom function in a child theme. To accomplish this, you will first need to setup a child theme then add the following code to the functions.php file of that theme:
```
function my_custom_head_output() {
  ?>
    ...code here...
  <?php
}

add_action( 'wp_head', 'my_custom_head_output', 99999 );
```
You can replace the sections that say …code here… with any code you need. You can choose between the two functions depending if you need your output in the <head> or near the closing <body> tag.

Thanks!

Fantastic. Thank you.

Just another quick questions. I have activated the included plugin ‘The Grid’. How do activate it. When I go to settings for ‘The Grid’ It says, ‘Not Activated’. Is there a serial number I have to add?

Thank you.

Hi there,

Thanks for writing in! The Grid is an Integrated Plugin of X. You don’t need to activate it to use with X and there is no license key provided for integrated plugins. However if you want the premium features (check their site) then you need to purchase a separate license from CodeCanyon.

P.S: The term “activation” is actually referring the license activation not the plugin.

Cheers!
