1. CSS/JS Conflicts

Your theme or other plugins’ styles/scripts might be overriding or conflicting with WooGallery.

Check:

• Inspect elements on the broken product page (Right-click > Inspect Element).
  
• See if any CSS rules are coming from your theme that’s overriding gallery layout.
  

Fix:

• Try disabling WooGallery’s built-in styles .
  
• Add custom CSS to override the problematic styles.

2. JavaScript Errors

Other plugins or your theme might be causing JavaScript errors that break layout rendering or gallery scripts.

Check:

• Open your browser console (F12 > Console tab) and look for errors.
  

Fix:

• If there are errors, they may be due to conflicts with other JS libraries or missing dependencies.
  
• You might need to dequeue conflicting scripts or ensure jQuery and WooCommerce scripts load correctly.

3. Outdated Theme or Plugin

If your WooCommerce theme or the WooGallery plugin is outdated or mismatched in versions, layout issues might happen.

Check:

• Update WooGallery, WooCommerce, and your theme to the latest versions.
  
• Ensure they’re all compatible (check plugin docs or support forums).
