How to Solve Joomla File Checksum Failed When Updating Joomla: Joomla frequently releases updates to improve security, add features, and fix bugs. However, during the update process, you might encounter the frustrating “File Checksum Failed” error.
Understanding the File Checksum Failed Error
When you attempt to update Joomla, the CMS checks the integrity of its core files to ensure that they have not been tampered with or corrupted. Joomla calculates a checksum (a unique code based on the file’s content) for each file and compares it to a predefined value. If the checksums do not match, Joomla will trigger the “File Checksum Failed” error to protect your website’s security.
Common Causes of the Error
Several factors can lead to the “File Checksum Failed” error during the Joomla update process:
- Wrong Absolute Path: The absolute path is a path containing the root director
- Corrupted Files: Sometimes, files in your Joomla installation might get corrupted due to various reasons, including server issues or malware infections.
- Incomplete Downloads: If the update files are not downloaded completely or correctly, checksum errors can occur.
- Custom Modifications: If you’ve made custom changes to the Joomla core files, the checksums will not match the expected values.
- Server Configuration: Server misconfigurations, security settings, or inadequate permissions might interfere with the file integrity check.
- Outdated Software: Outdated server software, PHP version, or Joomla itself can lead to checksum errors.
Now that we understand the causes of this error, let’s dive into how to resolve it.
