How to Fix the XAMPP Localhost index.php Error [Ultimate Guide]

Fix XAMPP Localhost index.php Error

XAMPP is an excellent open-source software that lets you install WordPress on your local machine to test new features, debug errors, and experiment with different configurations.

Similarly, you might have heard the term ‘’localhost/index.php’’ that suggests the ‘’index.php’’ file resides in a local web server’s root directory. Moreover, the ‘’index.php’’ file helps you appropriately access the WordPress sites.  

Coming back to the point, one of the common errors that many XAMPP users encounter is when they try to access localhost/xampp/index.php in their browser and get an error message instead.

Encountering this error can be frustrating and perplexing, particularly if you’re unsure about its causes and solutions. That’s why we’ve created this ultimate guide to help you understand and resolve the XAMPP localhost index.php error.

In this article, you’ll learn:

  • What does the XAMPP localhost/index.php error mean?
  • What causes the XAMPP localhost/index.php error?
  • How can the XAMPP localhost/index.php error be fixed using two simple solutions?

So, let’s dive in and get your XAMPP server running smoothly!

What does XAMPP localhost/index.php Error mean?

When you see an XAMPP Localhost index.php error message, it means an obstacle prevents your XAMPP server from accessing the index.php file, which serves as the default file when accessing the localhost URL.

The localhost/index.php or index.php file is a special file that serves as the entry point to your website. It contains the code that tells the browser what to display when someone visits your site.

When you install XAMPP, it creates a folder called htdocs in the C:\Xampp directory. This folder stores all your web files, such as HTML, CSS, PHP, images, etc. The htdocs folder also contains an index.php file that redirects you to the XAMPP dashboard when you visit “localhost/xampp/index.php” in your browser, which looks something like this:

However, sometimes when you try to access localhost/xampp/index.php in your browser, instead of seeing the XAMPP dashboard, you see an error message, as shown in the image below:

localhost xampp index.php Object not found error

Or sometimes, you see an error message which looks like this:

localhost xampp index php Object not found error

You can get these error messages for a number of reasons. That’s why it’s crucial to identify the exact cause in your setup to find the appropriate solution.

What Causes the XAMPP Localhost index.php Error?

Understanding the reason behind the XAMPP Localhost index.php error is crucial. Depending on the cause of the error, you may see different error messages in your browser. Here are some of the most common causes of why XAMPP Localhost index.php error occurs in the first place:

  • Missing, Deleted, or Moved index.php File: Sometimes, you accidentally delete, rename, or move it to another folder inside or outside the htdocs folder. As a result, the server fails to locate it when attempting to access the localhost URL.
  • Incorrectly Typed or Typo in the URL: If you forget to add a slash (/) at the end of the URL or misspell any part of it, the XAMPP server will not be able to find the index.php file. For example, if you type localhost/xampindex.php instead of localhost/xampp/index.php.
  • Corrupted or Modified XAMPP Configuration Files: The XAMPP configuration files, such as httpd.conf or php.ini, play a crucial role in the proper functioning of the server. If these files become corrupted or you modify them incorrectly, they can disrupt the accessibility of the index.php file, which ultimately leads to a XAMPP localhost index.php error.

No matter what the cause is, it is clear that you can’t access your local web server. But don’t worry! There are some simple solutions, which we will show you in the following section, that can help you fix this issue and get back to your work.

Why is it Necessary to Fix the XAMPP Localhost index.php Errors?

As a free development tool, developers used it locally for development and testing purposes. Having errors in XAMPP Localhost index.php can cause multiple other problems. So, fixing the localhost/index.php errors is essential for several reasons, including:

  • Uninterrupted Development & Testing

This free tool provides ease of development and testing to developers locally, but if there are errors in the file, the chances of a disrupted development environment become high. So, fixing this error will allow developers to continue their work without interruption and ensure effective project testing and a smoother development process.

  • Web Application Access

The index.php file often serves as the entry point for web applicants in XAMPP. If it’s not working correctly, the user cannot access the application they are developing or testing. So, if issues are fixed on time, it guarantees that web applications operate seamlessly.

  • Quality Assurance

Testing is one of the mandatory steps involved in software development. When the localhost/index.php file is inaccessible due to errors, it will become impossible to run thorough testing that will later result in software release with undetected bugs and issues.

How to Fix the XAMPP Localhost index.php Error (2 Simple Solutions)

Two ways to fix the XAMPP localhost index.php error are renaming the index.php file to index.txt or changing the DocumentRoot directory in XAMPP. Both solutions are easy to implement and can solve the problem in most cases.

However, before you try any of these solutions, ensure your XAMPP server is functioning correctly. To do that, open the XAMPP control panel from your Start menu or desktop shortcut and check if Apache and MySQL are running. They should have green indicators next to them like this:

XAMPP Control Panel

If they are not running, click the “Start” buttons located in the “Actions” column. Or, if they are already running but displaying red indicators or error messages, click the “Stop” buttons to start them again.

However, if everything is fine with your XAMPP server, then proceed with one of these solutions:

Solution #1: Rename index.php to index.txt

This solution involves changing the file extension of the localhost/index.php or index.php file from .php to .txt. This way, the browser will treat it as a plain text file instead of a PHP script and display its contents without encountering any errors.

Follow the below steps to rename the index.php file to index.txt using XAMPP Control Panel:

Step #1:

Open the XAMPP Contro Panel and click the Explorer button on the right., which will take you directly to the XAMPP folder.

Step #2:

Once inside the XAMPP folder, find the htdocs subfolder, where you will find the index.php file. If you use the Windows operating system, the file might be labeled simply as “index” because extensions are typically hidden by default.

The htdocs subfolder is under XAMPP folder

Step #3:

Check the box next to “File name extensions.” in the File Explorer ribbon to make file extensions visible. Enabling this option will display the file extensions to make renaming easier.

The index.php file is inside the “htdocs” folder, and enabling the extensions in Windows Explorer allows you to edit its name

Step #4:

Right-click the index.php (or index) file and choose the Rename option from the context menu. Delete the “php” extension and replace it with “txt”. If you receive a prompt asking if you want to change the file name, select Yes to proceed with renaming.

That’s it! Now open your browser and navigate to “localhost.” You should see the list of directories you created.

Solution #2: Change the DocumentRoot Directory in XAMPP

After changing the “index” file extension, if you are still facing the same issue. The next step is to edit the httpd.conf file in XAMPP to change its DocumentRoot directive to point to where your index.php file is located.

By default, XAMPP uses C:\Xampp\htdocs as its DocumentRoot directory. However, for some reason, if your index.php file is not in this folder or has been moved somewhere else, then XAMPP will not be able to find it and will show an error message instead.

Here are the steps to change the DocumentRoot Directory in XAMPP by editing the httpd.conf file:

Step #1:

Open the XAMPP Control Panel and click the Explorer button on the right.

Step #2:

Navigate to the appropriate directory to locate the httpd-vhosts.conf file:

  • On Windows, you can find the file at: “C:\xampp\apache\conf\extra\httpd-vhosts.conf”
  • On Mac, follow this path: “~/.bitnami/stackman/machines/xampp/volumes/root/etc/extra/httpd-vhosts.conf”

Once you have reached the desired directory, open the httpd-vhosts.conf file using a text editor such as Notepad, TextEdit, etc.

Step #3:

Within the httpd-vhosts.conf file, locate the “VirtualHost” sections and look for the line labeled “DocumentRoot.” If the path specified in this line ends at “htdocs,” it signifies the source of the issue. You need to change it by adding the path of your project so that it points to the folder corresponding to your project.

For instance, the original content of the file might seem like this:

The initial httpd-vhosts.conf file specifies htdocs in DocumentRoot under the VirtualHost section

Step #4:

On the “DocumentRoot” line, you should now enter the name of the folder containing your website’s files, usually under the “htdocs” folder. After making the necessary adjustments, the modified document should look something like as follows:

The updated version of httpd-vhosts.conf file with the path of your project

Now, make sure to save the changes to the file. Then, try to reload localhost/xampp/index.php to check if the issue has been resolved.
