PDF Generation Troubleshooting Guide

Common PDF Generation Issues

1. Blank PDF Files

If you're getting blank PDF files when generating invoices or other documents:

  • Ensure your PHP memory_limit is set to at least 128M in your php.ini file
  • Verify that the GD PHP extension is enabled on your server
  • Check if you have write permissions in the temp directory
  • Make sure all required fonts are properly installed

2. Missing Images or Logos

If images or your company logo aren't appearing in generated PDFs:

  • Confirm that your logo file exists in the correct directory
  • Verify the image file permissions (should be readable)
  • Try re-uploading your logo through Appearance → Customize
  • Use supported image formats (PNG, JPG, GIF)
  • Check if the image path in your custom template is correct

3. Character Encoding Issues

If you see question marks or incorrect characters in your PDFs:

  • Ensure you're using UTF-8 encoding in your system settings
  • If using a custom template, verify the encoding of your template file
  • Check if you're using a compatible font that supports your language characters
  • Try changing the PDF font in Settings → General Settings

Set a different font, and try loading pdf file again-
