help how to add {% comment %}{{content_for_header}}{% endcomment %} instead of{{ content_for_header

Shopify Discussion

Topic summary

A Shopify store owner is attempting to improve site speed by commenting out the {{ content_for_header }} Liquid tag in their theme.liquid file using {% comment %}{{ content_for_header }}{% endcomment %}.

The Problem:

  • While this change successfully increased page speed, it broke several store functions
  • Specifically affected: color swatches and recently viewed products section
  • The store (divarouj.com) now has non-functional features after the modification

Technical Context:

  • The {{ content_for_header }} tag is essential for Shopify’s core functionality
  • Commenting it out removes critical scripts and tracking codes that many features depend on
  • The user shared their theme.liquid code (which appears corrupted/reversed in the original post)

Current Status:
The discussion remains unresolved. One community member requested clearer information about what specific changes are desired and how things should work differently, but communication barriers persist. The fundamental issue is that commenting out content_for_header creates a trade-off between speed and functionality that cannot be easily resolved without alternative optimization approaches.

I’m not sure if I understand what you’re asking for here.

Anything you put between {% comment %} and {% endcomment %} tags is turned into a comment.

If you’re asking me to comment out the " {{ content_for_header }}" part, then this is how it would look:


{%- liquid

    assign iso_code_ck = iso_code | split: '-' | first
