Seems fine to me:
Am I misunderstanding?
Topic summary
Problem: On collection pages, the browser tab showed the URL instead of the collection name because the HTML title-tag was empty. This affected collection pages while other pages displayed correctly.
Cause: Likely caused by an SEO app modifying theme code/settings. One participant noted Brooklyn theme normally handles titles, implying an app override. A screenshot highlighted the empty title-tag.
Fix/Outcome: The original poster confirmed it was an SEO app issue; the app’s default setting had changed unexpectedly. Adjusting the SEO app’s settings restored proper titles. No code changes or step-by-step fix was posted.
Other inputs: Another participant reported the titles appeared fine on their end, suggesting variability (e.g., caching or timing). Additional users (using Debut theme and a product duplication workflow with Recharge) reported similar title mismatches and asked how to fix them, but did not receive a detailed solution.
Status: Resolved for the original poster by correcting SEO app settings; remains open for others seeking explicit steps. Central takeaway: check SEO app configurations and any theme modifications to the title-tag.
