Common Hummingbird Problems and How to Fix Them
Hummingbird is used on many WordPress websites. In most cases it works well, but problems can still happen after updates, plugin conflicts, or wrong settings.
Knowing the root cause of a problem is the fastest path to fixing it. Most WordPress plugin issues share a common pattern: something changed — an update, a new plugin, a server configuration tweak — and the site stopped behaving as expected. The good news is that these issues are almost always fixable, often in under ten minutes, if you follow the right steps.
Before diving into specific problems, it helps to understand how WordPress plugins interact with each other. Every plugin adds PHP code, often JavaScript, and sometimes CSS to your site. When two plugins load conflicting code — or when a theme’s JavaScript interferes with a plugin — things break. This is called a plugin conflict, and it is the leading cause of WordPress site issues worldwide.
Why Hummingbird Problems Happen
A common issue is that another plugin or theme does not work well with Hummingbird. This usually happens after a WordPress update.
The first thing to do is:
- Clear cache
- Update the plugin
- Test with the default theme
- Turn off other plugins one by one
Most Common Hummingbird Problems
The Plugin Stops Working After an Update
This is one of the most common problems. If the website worked before the update, there is probably a conflict.
The Page Loads Slowly
Many plugins add extra scripts. If your site becomes slow, use a cache plugin and remove plugins you do not need.

Forms, Buttons, or Checkout Stop Working
JavaScript errors often break forms or buttons. Open the browser console and check for errors.
Step-by-Step Fix
- Make a backup.
- Turn off all other plugins.
- Turn them back on one by one.
- Find the plugin causing the problem.
- Contact support if needed.
How to Use WordPress Debug Mode
WordPress has a built-in debug mode that reveals errors hidden from visitors. To enable it, open your wp-config.php file and set:
define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', false );
This writes errors to /wp-content/debug.log without showing them on screen. After reproducing your problem, check this file for error messages. They often point directly to the plugin or function causing the issue.
If you see a PHP fatal error from a specific plugin file, you know where to look. If you see JavaScript errors, open your browser console (F12) and look at the Console tab for red error messages.
Checking Server Requirements
Many plugin problems are actually server problems in disguise. Before blaming a plugin, verify that your server meets the minimum requirements:
Your hosting must run PHP 7.4 or higher (PHP 8.1+ is recommended for 2024). It also needs sufficient memory — WordPress itself needs at least 64MB, but most modern plugins work best with 256MB or more. You can check your PHP version by going to Dashboard → Tools → Site Health.
If your memory limit is too low, add this to your wp-config.php file:
define( 'WP_MEMORY_LIMIT', '256M' );
Always Test on a Staging Site First
One of the best practices any WordPress site owner can adopt is using a staging environment. A staging site is an exact copy of your live website where you can test updates, new plugins, and configuration changes without any risk to your live visitors.
Many managed WordPress hosting providers — such as Kinsta, WP Engine, and Cloudways — offer one-click staging environments. If your host doesn’t, you can create a staging site manually using a plugin like WP Staging or Duplicator Pro.
The workflow is simple: make your change on staging, verify everything works, then apply the same change to your live site. This single habit prevents the vast majority of WordPress emergencies.
FAQ
Should I replace Hummingbird?
Only if the plugin no longer gets updates or the same problem keeps coming back.
Can cache plugins break Hummingbird?
Yes. Cache plugins sometimes break dynamic pages like forms, checkout pages, and member areas.
How do I know if a plugin update caused my problem?
Check your site’s activity log. If you use a plugin like WP Activity Log or Simple History, you can see exactly when plugins were updated and correlate that to when your problem started. If you don’t have an activity log, WordPress stores update timestamps in the database — a developer can query these for you.
Is it safe to delete and reinstall a plugin?
In most cases, yes. Deleting a plugin removes its files but usually leaves its database tables intact. When you reinstall it, the plugin typically reconnects to its existing data. However, always make a backup first, because some plugins clean up their database tables when deleted.
What should I do if none of the fixes work?
If you have tried deactivating conflicting plugins, clearing cache, switching themes, and checking server requirements without success, it is time to contact the plugin developer’s support team. Provide them with your PHP version, WordPress version, list of active plugins, and any error messages from debug.log. Most plugin support teams are very responsive and can diagnose unusual issues quickly.
Can plugin conflicts cause data loss?
Plugin conflicts very rarely cause data loss on their own. However, the panic of a broken site sometimes leads people to take actions — like deleting tables or restoring old backups — that do cause data loss. Always back up before troubleshooting, and never delete database tables unless you are certain they are unused.
How many plugins is too many?
There is no hard limit, but quality matters more than quantity. A site with 40 well-coded plugins can outperform a site with 15 poorly optimized ones. The real concern is overlapping functionality — having two plugins that do the same job wastes resources and creates conflict risk. Audit your plugins regularly and remove anything you are not actively using.
