How to fix WordPress checksum error?

A checksum is a value used to verify the integrity of a file. When the checksum of the downloaded file doesn’t match the expected value, WordPress will halt the update process to prevent potential issues.

Here’s how you can address this problem:

1. Manual Update:
   • Download the latest version of the Astra theme directly from the official website or the source you purchased it from.
   • Access your WordPress website’s files using an FTP client or your wordpress hosting cPanel’s File Manager.
   • Navigate to wp-content/themes/.
   • Rename the existing astra folder to astra_old as a backup.
   • Upload the new version of the Astra theme that you’ve downloaded.
   • Once uploaded, go to your WordPress dashboard and activate the Astra theme.
2. Clear Cache:
   • Sometimes, caching can interfere with the update process. Clear your website’s cache using any caching plugin you might have installed. Also, clear your browser’s cache.
3. Check File Permissions:
   • Ensure that the file permissions for the wp-content and wp-content/themes directories are set correctly. Typically, directories should be set to 755 and files to 644.
4. Re-try the Update:
   • After clearing the cache and checking file permissions, try updating the theme again from your WordPress dashboard.
5. Contact Support:
   • If you’ve tried the above steps and are still facing issues, it’s a good idea to contact the Astra theme support team or your hosting provider. They might be aware of the issue and can provide a solution.
6. Check for Plugin Conflicts:
   • Deactivate all plugins and try updating the theme again. If the update is successful, reactivate the plugins one by one to identify any potential conflicts.

Remember to always backup your website before making any changes. This ensures that you can quickly restore your site to its previous state if something goes wrong.
