## What it means

A code file your product page loads failed Rabbot's syntax check. A browser stops running a file at a syntax error, and a syntax check cannot tell which part of the page that file controls.

## What to do

Usually a theme file edit or an app update. Open the product page on a phone and on a computer and add it to the cart. Rabbot checks the file again when it changes and closes this once it passes.
