Hi, I’ve inherited a website from a previous developer. I have script tags in the \<head\> and I don’t know how or where they are being injected?

Can anyone point me to where I might find them? I cannot find them in the Design Manager

Hi @LBernardo86. What you’re mentioning is should be from _standard\_header\_includes_ HubL variables. This is required for HubSpot CMS Hub tempalets, inserts automatically tracking code, meta tags, link tags, script tags, and so on. The document about _standard\_header\_includes_ is here: [HubL variables - HubSpot docs](https://developers.hubspot.com/docs/cms/hubl/variables#required-page-template-variables)

Script tags that will be inserted is generally from these:

- JavaScript code on Custom Modules（①）
- JavaScript file in Design Manger referenced by Custom Module（②）
- Codes in templates with [require\_js](https://developers.hubspot.com/docs/cms/hubl/tags#require-js) HubL tag.
