Displaying Header Data on Google: Understanding and Fixing Undefined Function Errors
As a website owner or developer, you may have come across a frustrating situation where Google displays an error message in the search result excerpt for your page. This can be puzzling and concerning, as it suggests there's an issue with your site that's being picked up by the Google crawler.
One common error message you might see is:
"Fatal error: Uncaught Error: Call to undefined function elegant_description() in /home/armonisencia/public_html/site/wp-content/themes/DIVI/header.php:16 Stack trace: #0 /home/armonisencia/public_html/site/wp-includes/template.php(688): require_once() #1 …"
This error message is telling you that the Google crawler has encountered a problem on your site, specifically that it's trying to use a function called elegant_description()
in your header.php
file, but that function doesn't actually exist.
In this article, we'll dive deeper into what this error message means, why it's appearing, and how you can go about fixing the issue to ensure Google can properly display your site's data in search results.
Understanding the Error Message
Let's break down the key elements of the error message:
-
"Fatal error: Uncaught Error:" This indicates that the Google crawler encountered a critical problem on your site that prevented it from successfully processing the page.
-
"Call to undefined function elegant_description()" This is the crux of the issue. The crawler is attempting to call a function called elegant_description()
, but that function doesn't exist in your code.
-
"/home/armonisencia/public_html/site/wp-content/themes/DIVI/header.php:16" This tells you the specific file and line number where the error is occurring – in this case, it's line 16 of the header.php
file in the DIVI WordPress theme.
-
"Stack trace:" This provides additional technical details about the error and the sequence of events that led to it.
The key takeaway here is that the Google crawler is trying to access some data or functionality in your site's header, but it's encountering an issue because the function it's trying to use doesn't exist. This is preventing the crawler from successfully processing your page and displaying the appropriate information in the search result.
Why is Google Showing this Error?
Google's web crawler, known as Googlebot, is constantly scanning the internet to index and catalog web pages. As part of this process, Googlebot will attempt to access various elements of a website, including the header, to gather information that can be used to display rich snippets and other data in search results.
When Googlebot encounters an error like the one we're discussing, it means that there's an issue with your site's code that's preventing the crawler from accessing the data it's looking for. In this case, the error is specifically related to a function call in the header.php
file that doesn't actually exist.
It's important to note that Google doesn't necessarily crawl and index websites instantly. In fact, it can take up to 30 days for Google to re-crawl a site and update the information it has stored. This means that the error message you're seeing in the search results may not be reflecting the current state of your website.
Fixing the "Call to Undefined Function" Error
Now that we understand the root cause of the error, the next step is to fix it. Here's how you can go about that:
-
Identify the Problematic Function: The first thing you'll want to do is locate the line of code in your header.php
file that's causing the error. In the example we're using, the error is occurring on line 16, and it's related to a function called elegant_description()
.
-
Check Your Theme's Functions: Depending on the WordPress theme you're using, the elegant_description()
function may be defined in a separate file, such as functions.php
. Search through your theme's files to see if you can locate where this function is defined. If you can't find it, then it's likely that the function doesn't actually exist.
-
Remove or Replace the Function Call: If the elegant_description()
function doesn't exist, you'll need to remove the call to it from your header.php
file. Alternatively, you could replace the function call with a different, valid function that serves a similar purpose.
-
Test and Validate the Changes: After making the necessary changes to your header.php
file, be sure to test your site to ensure that everything is working as expected. You can use tools like the WordPress Theme Test Suite to help validate your changes.
-
Request a Google Recrawl: Once you've fixed the issue, you'll want to request that Google recrawl your site. You can do this through the Google Search Console, which provides a tool that allows you to submit URLs for immediate recrawling.
By following these steps, you should be able to identify and fix the "Call to undefined function" error that's causing issues with how your site's data is displayed in Google search results.
Preventing Future Errors
To help prevent similar issues from occurring in the future, here are some best practices to keep in mind:
-
Keep Your WordPress Theme and Plugins Up-to-Date: Outdated themes and plugins can often lead to compatibility issues and errors. Make sure to regularly update your WordPress installation, theme, and plugins to ensure you're running the latest stable versions.
-
Test Changes Thoroughly: Whenever you make updates or changes to your website's code, be sure to thoroughly test those changes to ensure they don't introduce any new errors or issues.
-
Use Robust Error Handling: Implement proper error handling in your WordPress theme and plugin code to ensure that any errors that do occur are properly logged and displayed to you, the site owner, rather than being shown to your website visitors.
-
Monitor Your Site's Performance and Health: Use tools like Google Search Console, Google Analytics, and website monitoring services to keep a close eye on your site's performance, security, and overall health. This can help you identify and address issues before they become problems.
By following these best practices, you can help ensure that your website's data is properly displayed in Google search results, and that any errors or issues that do arise can be quickly identified and resolved.
