Common Errors

Solutions for common errors and issues with product feeds.

Feed Generation Errors

”Memory limit exhausted”

Your server ran out of memory during feed generation.

Solutions:

  1. Increase PHP memory limit in wp-config.php:

    define('WP_MEMORY_LIMIT', '256M');

  2. The plugin handles large catalogs efficiently, but if issues persist, contact your host to increase memory limits

”Maximum execution time exceeded”

Feed generation took too long.

Solutions:

  1. Enable background processing (works in chunks, avoiding timeouts)

  2. Reduce feed size with filters:

    • Exclude out-of-stock products
    • Filter to specific categories
    • Remove unnecessary products

  3. Increase PHP max_execution_time (ask your host)

“Failed to write feed file”

The plugin couldn’t save the feed file.

Solutions:

  1. Check file permissions on /wp-content/uploads/product-feeds/

    • Should be writable (755 or 775)

  2. Verify disk space is available

  3. Check for security plugins blocking file writes

”Invalid feed URL”

The feed URL isn’t accessible.

Solutions:

  1. Verify the URL works in your browser
  2. Check for security plugins blocking access
  3. Ensure .xml or .csv files aren’t blocked
  4. Test with a simple URL (no query parameters)

Google Merchant Center Errors

”Missing required attribute: gtin”

Google requires GTIN for products from known brands.

Solutions:

  1. Add GTINs to products:

    • Edit product → Product Feed tab → Enter GTIN

  2. Use Smart Auto-Fill for suggestions

  3. For custom products without GTINs:

    • In feed settings, set identifier_exists to “no"

"Invalid GTIN”

The GTIN format is incorrect.

Solutions:

  1. Verify GTIN is correct:

    • UPC: 12 digits
    • EAN: 13 digits
    • ISBN: 13 digits

  2. Check for typos or extra characters

  3. Validate using an online GTIN checker

”Landing page error”

Google couldn’t access your product page.

Solutions:

  1. Verify product URL works publicly
  2. Check for password protection
  3. Ensure robots.txt allows Googlebot
  4. Check SSL certificate is valid
  5. Remove any geographic restrictions

”Price mismatch”

Feed price doesn’t match landing page price.

Solutions:

  1. Regenerate feed after price changes

  2. Check for caching issues:

    • Clear WooCommerce cache
    • Clear page cache
    • Clear CDN cache

  3. Verify tax settings match:

    • Feed and site should both include or exclude tax
    • Check your region’s requirements

  4. For variable products, ensure correct price shows

”Image too small”

Product image doesn’t meet size requirements.

Solutions:

  1. Google requires minimum 100x100 pixels
  2. Recommended: 800x800 pixels or larger
  3. Re-upload larger images to products
  4. Check image URLs are accessible

”Policy violation”

Product violates Google’s policies.

Common issues:

  • Misleading claims
  • Inappropriate content
  • Trademark issues

Solutions:

  1. Review Google Merchant policies
  2. Remove or modify violating products
  3. Filter problematic items from feed
  4. Appeal if you believe it’s an error

”License key invalid”

Your Pro license wasn’t recognized.

Solutions:

  3. Verify license hasn’t expired
  4. Try deactivating and reactivating
  5. Contact support with your purchase email

”Could not connect to license server”

Your server can’t reach our API.

Solutions:

  1. Check outbound HTTPS is allowed
  2. Verify no firewall blocking api.wooplugin.pro
  3. Ensure SSL/TLS is working
  4. Try again later (temporary server issues)

“Settings not saving”

  4. Clear browser cache and reload

Data Issues

Products missing from feed

    • Image
    • Stock status

  4. Regenerate the feed

Wrong prices in feed
