Topic summary
Users are experiencing persistent Laybuy payment method displays on their Shopify product pages even after uninstalling the app. Simply removing the app from the Shopify admin doesn’t eliminate leftover code in the theme.
Proposed Solutions:
- Contact app developers directly or through Shopify support to request complete removal
- Manual code removal (multiple approaches reported):
- Navigate to Apps → “Develop app for your store” → App Development page to delete
- Delete two Laybuy.liquid files from Templates folder, plus line 194 in Theme.liquid
- Remove two laybuy.helper files from the Assets folder in theme code
Key Issue: Apps that modify themes often leave behind scripts and template files that continue displaying functionality after uninstallation. Users must manually locate and delete these remnants from their theme code editor.
The discussion remains open with community members sharing different successful removal methods, suggesting file locations may vary by theme or app version.
