Why Are My NextGEN Gallery Shortcodes Not Working? Common Issues and Fixes

30 threads Sep 10, 2025

If you're using the 'Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery' plugin, you've likely encountered a frustrating issue: a gallery shortcode that just won't behave as expected. This is a common problem reported by many users, and it can manifest in several ways, from galleries not displaying at all to showing outdated content or incorrect pagination.

Why Do Shortcode Problems Happen?

Shortcode issues in NextGEN Gallery can stem from a variety of sources. The most common causes include incorrect shortcode syntax, conflicts with other plugins or themes, and caching mechanisms—either from a plugin or your server—that serve old content. Understanding the root cause is the first step to finding a solution.

Common Shortcode Issues and How to Fix Them

1. The "We cannot display this gallery" Error

This error often appears when the shortcode syntax is incorrect or references a gallery ID that doesn't exist.

  • Solution: First, simplify your shortcode to its most basic form to test if the gallery itself exists and can be displayed. For example, change a complex shortcode like [ngg src="galleries" ids="1" display="basic_thumbnail" order_by='rand()'] to a simpler version: [ngg src="galleries" ids="1" display="thumbnail"]. If the simple shortcode works, the issue is likely with one of the added parameters. If it doesn't, verify the gallery ID is correct in your NextGEN Gallery admin area.

2. Shortcode Shows Different or Outdated Content on Different Pages

You might find that the exact same shortcode displays the correct, up-to-date gallery on a regular page but shows an old, cached version on your homepage.

  • Solution: This is almost always a caching issue. Even if you don't have a caching plugin installed, your web host might use server-level caching.
    1. Conflict Test: Temporarily deactivate all other plugins except NextGEN Gallery and switch to a default WordPress theme (like Twenty Twenty-Four). If the problem is resolved, reactivate your plugins one by one to identify the culprit.
    2. Clear Caches: Clear any caching from your plugins (e.g., WP Rocket, W3 Total Cache) and ask your hosting provider to clear any server-side caches.

3. Pagination Problems and Multiple Galleries on One Page

A frequent issue is that pagination controls for one gallery affect all other galleries on the same page, making it impossible to navigate them independently.

  • Solution: This is a known limitation in how pagination is handled. The 'Photo Gallery, Sliders, Proofing and Themes – NextGEN Gallery' team has acknowledged this behavior. Unfortunately, there is no simple setting to change this. Your best workaround is to avoid using pagination for multiple galleries on a single page. Instead, consider using a display type that shows all images at once or using a different gallery plugin for pages where this functionality is critical.

4. Shortcodes Not Working in Custom Post Types or Page Builders

Your shortcode might work perfectly in a standard post but fail to display correctly within a custom post type or a third-party page builder like Divi or Elementor.

  • Solution:
    1. Ensure the custom post type or page builder supports the use of WordPress shortcodes. Most do, but some may require enabling the feature.
    2. Perform a conflict test by deactivating all plugins except NextGEN Gallery and the plugin that creates your custom post type. This will help you determine if another plugin is causing a conflict.

General Troubleshooting Tips

  • Double-Check Your Syntax: A single misplaced quote or typo in a shortcode parameter can break the entire gallery. Pay close attention to the use of straight quotes (") versus curly quotes (”), as this is a common mistake.
  • Use the Block Editor: Whenever possible, use the dedicated NextGEN Gallery block in the WordPress block editor (Gutenberg) to insert galleries. This helps avoid syntax errors and often provides a visual interface to customize display settings.
  • Check for Known Limitations: Some features, like advanced tag filtering with AND logic or AJAX tag filtering, are not available in the free version of the plugin. The sample threads indicate that the development team often registers these as feature requests for future consideration.

By methodically testing your shortcodes and following these troubleshooting steps, you can resolve the majority of display issues and get your galleries working as intended. If problems persist, searching for your specific error message on independent troubleshooting forums can often yield solutions from other users who have faced the same challenge.
