Troubleshooting & Debugging
Learn how to fix common errors and debug your theme effectively.
Things will break. Knowing how to identify and fix common issues is a crucial skill for any developer.
The Dreaded "Could not parse XML" Error
This is the most common error. It means you have a syntax mistake in your XML. Usually, it's caused by an unclosed tag, an illegal character (`&`, `<`) outside of a CDATA block, or a typo in a `b:` tag.
Debugging Tips
- Check the Browser Console: Open your browser's developer tools (F12 or Ctrl+Shift+I) and check the Console for JavaScript errors.
- Comment Out Code: If you can't find the error, start commenting out recent changes until the theme saves successfully. This helps you isolate the problematic code block.
- Use an XML Validator: You can copy your theme code and paste it into an online XML validator, which can often point you to the exact line with the syntax error.
