If you’ve encountered the white screen of death on your WordPress site and discovered the following fatal errors after enabling WP_DEBUG in your wp-config file, here’s a step-by-step guide to troubleshoot and resolve the issue.
1. Locate and Address Missing File:
The first error indicates a missing file, “class-wp-duotone.php.” Follow these steps:
- Access your WordPress installation directory.
- Navigate to “/wp-includes/” and check if the file “class-wp-duotone.php” exists.
- If the file is missing, download a fresh copy of WordPress from wordpress.org and upload the missing file to the “/wp-includes/” directory.
2. Check File Permissions:
Ensure that file permissions are set correctly:
- Verify that the file permissions for “class-wp-duotone.php” allow for reading and execution. Typically, setting the permissions to 644 should suffice.
3. Resolve the Second Fatal Error:
The second fatal error is related to the failed inclusion of “class-wp-duotone.php.” Here’s what you should do:
- Confirm that the file path in your “wp-settings.php” file is correct.
- Check for any typos or errors in the file path.
- Ensure that the file “class-wp-duotone.php” is present in the specified location.
4. Address the Third Fatal Error:
The third fatal error involves a function call on a null object. To resolve this:
- Open the “l10n.php” file located in “/wp-includes/”.
- Navigate to line 784 and inspect the code.
- Ensure that the load_textdomain() function is properly structured and receiving the correct parameters.
5. Check Language Files:
The error mentions loading text domains, so confirm the integrity of your language files:
- Verify that language files for your WordPress installation are intact and located in the specified directories.
- If needed, download the language files from WordPress Language Packs and replace the existing files.
After implementing these steps, refresh your WordPress site. If the white screen persists, review your changes and seek further assistance if necessary.
