If you are a website owner or developer, you know how important it is to keep your website running smoothly. One of the most common issues that can affect the performance and functionality of a website is PHP errors. These errors can be caused by a variety of factors, including coding issues and server configuration problems.
Fortunately, cPanel provides several tools and features to help you troubleshoot and resolve PHP errors quickly and efficiently. In this article, we will explore the different ways you can locate PHP errors in cPanel, including accessing error logs, enabling error display, and using various cPanel tools. We will also discuss common PHP error codes, best practices for preventing errors, and when it may be necessary to hire a professional for troubleshooting.
Accessing the cPanel Error Logs
When it comes to finding PHP errors in cPanel, the error logs are the primary location to check. These logs contain detailed information about errors that occur on your website, including PHP errors.
To access the error logs in cPanel, follow these steps:
- Log in to your cPanel account.
- Scroll down to the “Metrics” section and click on “Raw Access Logs.”
- Select the domain you want to view the logs for and click “Download.”
- The downloaded file will contain all of the raw access logs for the selected domain, including the error logs.
Once you have accessed the error logs, you can use them to identify specific PHP errors that are occurring on your website. These errors will be listed in the log along with information about the time they occurred, the location of the error, and other relevant details.
It’s important to note that the error logs can be difficult to read and interpret, especially if you’re not familiar with the format. However, with some practice and a basic understanding of PHP, you can use the logs to troubleshoot and resolve errors on your website.
Viewing PHP Errors in cPanel
Another way to locate PHP errors is by enabling PHP error display in cPanel. This will display any errors directly on the website page, making it easier to identify and resolve the issue.
To enable PHP error display, follow these steps:
- Log in to your cPanel account
- Scroll down to the “Software” section and click on “Select PHP Version”
- Click on the “Switch To PHP Options” link
- Scroll down to the “error_reporting” option and select “E_ALL”
- Scroll down and click the “Save” button
Once this is done, any PHP errors will be displayed directly on the website page. It’s important to note that leaving error display enabled on a production website is not recommended, as it can reveal sensitive information to site visitors. It’s best to disable error display once the issue has been resolved.
Common PHP Error Codes
PHP errors can be frustrating to troubleshoot, but knowing the most common error codes and their meanings can make the process easier. Here are some of the most frequently encountered PHP errors:
|Parse error||Syntax error in PHP code, such as a missing semi-colon or bracket.|
|Undefined variable||A variable is used without being declared or assigned a value.|
|Function undefined||A function is called that does not exist or has not been defined.|
|Class not found||A class is referenced that does not exist or has not been defined.|
|Cannot modify header information||Headers have already been sent to the browser, so modifying them is not possible.|
|Division by zero||Attempting to divide a number by zero.|
These errors can occur for various reasons, such as typos, missing code, or incorrect use of functions or variables. It’s important to carefully review the affected code and debug to identify the root cause of the error.
Troubleshooting PHP Errors with cPanel Tools
CPanel provides a range of tools that can be used to troubleshoot and resolve PHP errors. These tools are designed to help developers and website owners identify the root cause of errors and take the necessary steps to fix them. In this section, we’ll provide an overview of the most commonly used cPanel tools for PHP error troubleshooting.
The Error Log is the primary location for PHP errors in cPanel. It provides a detailed record of all errors that have occurred on the website, along with the date and time of each occurrence. To access the Error Log, go to cPanel > Metrics > Errors.
|Error Log Location||Common Uses|
|/usr/local/apache/logs/error_log||Logs all errors that occur on the server.|
|/home/username/public_html/error_log||Logs all errors that occur on the specified domain or subdomain.|
The PHP Modules tool allows you to view and modify the modules that are loaded for your website’s PHP installation. This can be useful for troubleshooting errors that are caused by missing or incompatible modules. To access this tool, go to cPanel > Software > Select PHP Version > View Current PHP Configuration > Extension Options.
The PHP Info tool provides detailed information about your website’s PHP installation, including which modules are installed and which settings are configured. This can be useful for identifying errors that are related to PHP configuration or version compatibility. To access this tool, go to cPanel > Software > Select PHP Version > PHP Info.

By utilizing these cPanel tools, you can troubleshoot and resolve PHP errors quickly and efficiently. Remember to always make a backup of your website before making any changes, and to test any changes in a development environment before deploying to a live website.
How to Fix White Screen of Death Errors
The white screen of death (WSOD) is a common PHP error that can occur for a variety of reasons, such as a syntax error, a plugin conflict, or a memory limit issue. When this error occurs, the website appears as a blank white page, making it impossible for users to access content or navigate the site. In this section, we will discuss how to troubleshoot and resolve the WSOD error using cPanel tools.
Step 1: Check Error Logs
The first step in resolving the WSOD error is to check the cPanel error logs for any PHP errors. As mentioned earlier in this article, the cPanel error log is the primary location for PHP errors and can be accessed through the cPanel interface. Look for any error messages that may be related to the WSOD error and take note of the specific error code.
Step 2: Disable Plugins
If the error log indicates that a plugin conflict may be causing the WSOD error, the next step is to disable all plugins and then reactivate them one at a time until the error is resolved. This can be done through the cPanel plugin manager, which allows you to easily enable or disable plugins with a single click.
Step 3: Increase Memory Limit
If the error log indicates that a memory limit issue may be causing the WSOD error, the next step is to increase the memory limit for PHP. This can be done through the cPanel PHP settings, which allow you to adjust the memory limit and other PHP settings as needed. It is important to note that increasing the memory limit may impact the overall performance of your website, so it should be done with caution.
Step 4: Check Syntax Errors
If the error log indicates that a syntax error may be causing the WSOD error, the next step is to check the code for any errors or typos. This can be done through the cPanel code editor, which allows you to easily edit and make changes to your website’s code. It is important to carefully review the code to ensure that all syntax errors are corrected before saving and updating the website.
In conclusion, the white screen of death error can be a frustrating and confusing issue to troubleshoot. By following these steps and using the tools available in cPanel, you can quickly identify and resolve the issue, ensuring that your website remains accessible and functional for your users.
Best Practices for Preventing PHP Errors
Preventing PHP errors is essential for maintaining optimal website performance and functionality. Here are some best practices to follow:
