[HELP] Visitors not tracked by Shopify system!

Technical Q&A

Topic summary

Multiple Shopify store owners are experiencing a critical analytics tracking failure where visitor counts have dropped dramatically (80-90%) despite actual traffic continuing normally. The issue began appearing 1-2 weeks ago for different users.

Key symptoms:

  • Shopify dashboard showing drastically reduced visitors (e.g., 800/day → 20/day)
  • Google Analytics also affected, showing minimal sessions
  • Ad platforms (Google Ads, Facebook Ads) still reporting normal click volumes
  • Only direct traffic or post-cart sessions being tracked
  • Conversion rates appearing artificially inflated (20% vs normal 2-3%)

Root cause identified:

  • The {{ content_for_header }} code in theme files has been modified or corrupted
  • Specifically affects “monorail and trekkie events on page loads” (Shopify’s tracking scripts)
  • Often occurs after theme updates or switches

Potential solutions:

  • Check if {{ content_for_header }} has been commented out or modified in theme.liquid
  • Contact theme developer to restore unedited version
  • Shopify acknowledges this as a known bug they’re addressing
  • Some users report the issue self-resolved after several days

Current status: Ongoing issue for many users, with Shopify support providing inconsistent responses. Some cases resolved, others still waiting after 3+ weeks.

same here started 2 days ago, I modified all my ads thinking its a problem with the link there, and spoke 2 a service person on Shopify who told me to check my domain provider … wasn’t that either… so yeah very strange what is happening hope they are coming with a solution soon,

can I use something else as analytics, is it reliable? also are the ads affected by this?
