How to Fix the “Whoa! Something Went Wrong” Error in LifterLMS Settings

Overview

# Top

If you see the message “Whoa! Something went wrong there! Please refresh the page and retry” when saving your LifterLMS settings, it can feel like something has broken, but in most cases, it hasn’t.

This error is usually caused by a security check failing behind the scenes, not a problem with your courses, settings, or data. Your site and data are still intact, and the issue can be resolved with a small adjustment.

This guide walks you through a simple fix so you can get back to saving your settings and continuing your work without disruption.

Why This Error Happens

# Top

This happens when the LifterLMS security system can’t verify the request sent to the server. Developers call this a “nonce verification” failure.

While this looks like a plugin conflict, it’s usually caused by how your hosting server communicates with WordPress. This is common on certain hosting providers such as GoDaddy.

To fix this, you’ll need to tell LifterLMS to use a different method to identify your server environment. You can do this by adding a small PHP code snippet to your site.

How to Fix the Error Using a Code Snippet

# Top

Follow these steps to apply the fix to your WordPress site.

Install a code snippets plugin if you don’t already have one. You can learn more about this in our guide on how to add custom code to LifterLMS.
Navigate to the snippets section in your WordPress dashboard. If you’re using the Code Snippets plugin, go to Code Snippets > + Add Snippet.
Choose the “Add Your Custom Code (New Snippet)” option and click the Use snippet button.
Set the “Code Type” to “PHP Snippet” using the dropdown menu.
Copy and paste the following code into the “Code Preview” box:

add_filter( 'llms_use_server_for_environment_fetch', '__return_true' );

Give your snippet a title, such as “Fix LifterLMS Settings Save Error.”
Toggle the switch to Active and click the Save Snippet button.
Go back to your LifterLMS settings and try to click Save Changes again.
