I am looking for a plugin, I need to add a script from Leadworx to the body of my site, so I was hoping for a plugin solution if anyone can recommend a good one?

Cheers,
Beven

Could you give me some more details about what code would you like to add? If this is only about some CSS, you can use a plugin like Custom Body Class to add a new class to the body.

I was told that I should add the code to the body of my website:

The code looks like this:
<script src=”//adpxl.co/HPBuqjmK/an.js”></script><noscript></noscript>
