Troubleshooting Common Markdown Editor Issues
Solutions for typical challenges when using online markdown editors:
Code Blocks Not Highlighting
Ensure your code block uses correct syntax: ```javascript (not ```js). Check that the language identifier is spelled correctly - the preview will show plain text for unrecognized languages.
Export Issues
For PDF export problems, ensure your browser allows downloads. Large documents with many images or tables may take a moment to process. Try exporting smaller sections if you encounter timeouts.
