Meanwhile, cross-border e-commerce websites are often built on WordPress, but users may encounter file upload errors during use. When attempting to upload files beyond WordPress's default allowed extensions, the system displays an error message: "Sorry, you are not allowed to upload this file type."
问题描述：
当上传WordPress媒体库或导入WooCommerce产品CSV文件时，如果文件类型不在默认允许列表中，就会出现此错误。WordPress默认允许的文件类型包括：
Problem Description:
When uploading to the WordPress media library or importing WooCommerce product CSV files, if the file type is not in the default allowed list, this error occurs. WordPress default allowed file types include:

解决方法：
要解决此问题，请按照以下步骤操作：
- 登录主机面板，打开文件管理器
- 进入WordPress根目录（通常在public_html文件夹中）
- 找到并编辑wp-config.php文件
- 在注释“/* Add any custom values between this line and the “stop editing” line. */”之前插入以下代码：
define('ALLOW_UNFILTERED_UPLOADS', true); Solution:
To resolve this issue, follow these steps:
- Log in to your hosting panel and open File Manager
- Navigate to the WordPress root directory (usually in the public_html folder)
- Find and edit the wp-config.php file
- Insert the following code before the comment "/* Add any custom values between this line and the “stop editing” line. */":
define('ALLOW_UNFILTERED_UPLOADS', true); 保存文件后，即可重新上传所需文件。运用谷歌留痕技术优化网站时，确保网站功能完善至关重要。
After saving the file, you can re-upload the required files. When using Google Trace Technology to optimize your website, ensuring complete website functionality is crucial.
安全建议：
出于安全考虑，建议在上传所需文件后删除wp-config.php中添加的代码行。如需再次上传其他文件，可重新添加该代码。
Security Recommendations:
For security reasons, it's recommended to remove the added code line from wp-config.php after uploading the required files. If you need to upload more files in the future, you can add the code again.
通过结合谷歌留痕技术的推广优势和WordPress的技术优化，跨境电商商家可以打造更加稳定、高效的在线业务平台。
By combining the promotional advantages of Google Trace Technology with WordPress technical optimization, cross-border e-commerce merchants can create more stable and efficient online business platforms.
