In terms of our prediction, this sounds like “Ghost Code” from a deleted app or a missing asset.
To fix the Liquid Error:
Go to Online Store > Themes > Edit Code. Open theme.liquid (or the file named in the error) and use Ctrl+F to search for the specific text shown in the error message. Simply delete that line of code to stop the warning.
To fix Broken Images:
Go to Content > Files in your admin. If an image was deleted or renamed, the code breaks. Ensure the filename referenced in your theme matches the actual file name in your settings exactly to fix the loading issue and layout shift.
We hope this could help! Could you please provide your store URL and collaborator code? That way, we can take a closer look at the error logs and identify exactly what is broken for you.
