Error 510 when edit and save snippets

Hi @haraldkrause

This error often arises from server-related problems, such as insufficient storage space or misconfigured server settings.

Possible Causes and Solutions:

1. Server Storage Limitations: Ensure your server has adequate storage space. A full disk can prevent saving new data, leading to errors like 510.
2. Server Configuration Issues: Verify that your server’s configuration aligns with the most recent WordPress requirements. Misconfigurations can cause unexpected errors.
3. Mixed Content Warnings: Some resources are being loaded over HTTP instead of HTTPS. This can cause browsers to block certain resources, potentially affecting plugin functionality. To resolve this, ensure all your site’s resources are served over HTTPS. You can use plugins like SSL Insecure Content Fixer to help address these issues.

Next Steps:

• Check Server Storage: Confirm that your server has sufficient free space. If it’s full, consider cleaning up unnecessary files or upgrading your hosting plan.
• Review Server Configuration: Consult with your hosting provider to ensure your server settings are compatible with WordPress and the Code Snippets plugin.
• Address Mixed Content Warnings: Use tools or plugins to identify and fix mixed content issues on your site. This will help ensure all resources are loaded securely over HTTPS.

Additionally, when adding PHP snippets in the Code Snippets plugin, you don’t need to include the <?php and ?> tags as these are handled automatically. So add your PHP code directly.

If the issue persists after these steps, please provide additional details or contact your hosting provider for further assistance, as your issue doesn’t seem related to Code Snippets.

Best,
Pau.
