Causes of “This file type is not permitted for security reasons” error

The “This file type is not permitted for security reasons” error typically occurs due to certain security restrictions imposed by WordPress. Let’s take a closer look at some of the common causes of this error:

WordPress security restrictions

WordPress has built-in security measures to protect websites from potential threats. One of these measures is the restriction on certain file types that are considered potentially dangerous. If you try to upload a file with an extension that is not allowed by WordPress, you will encounter this error.

Incorrect file permissions

File permissions determine who can access and modify files on a server. If the file you are trying to upload has incorrect permissions set, WordPress may consider it a security risk and prevent the upload.

Plugin conflicts

In some cases, conflicts between WordPress plugins can lead to the “This file type is not permitted for security reasons” error. Plugins that modify the file upload process or alter security settings can interfere with the normal functioning of WordPress and trigger this error.

How to fix the “This file type is not permitted for security reasons” error

Now that we understand the causes of the error, let’s explore the step-by-step solutions to fix it:

  1. Verify file type restrictions: Check the list of file types allowed by WordPress and ensure that the file you are trying to upload has a permitted extension. If not, you can either change the file type or use a plugin that allows additional file types.Wordpress-Error-Fix-wordpress-supported-file-types
  2. Adjust file permissions: Make sure the file you want to upload has the correct file permissions. The recommended file permission for most files is 644, while directories should have a permission of 755. You can adjust file permissions using an FTP client or through your hosting provider’s file manager.
  3. Disable conflicting plugins: Temporarily deactivate any plugins that modify the file upload process or security settings. Once disabled, try uploading the file again. If the error disappears, it indicates that one of the plugins was causing the conflict. You can then narrow down the problematic plugin by reactivating them one by one.
  4. Update WordPress and plugins: Keeping your WordPress installation and plugins up to date is crucial for maintaining website security and compatibility. Outdated versions can have security vulnerabilities and may not support certain file types. Regularly check for updates and apply them to ensure a smooth uploading process.
  5. Optimize website performance: Slow or overloaded websites can sometimes trigger security restrictions in WordPress. Optimize your website by using caching plugins, optimizing images, and ensuring efficient coding practices. A well-performing website is less likely to encounter file upload errors.

Remember, before making any changes to your website, it’s essential to create a backup. This ensures that you can restore your website to its previous state if anything goes wrong during the troubleshooting process.

Best practices to avoid the “This file type is not permitted for security reasons” error

Prevention is always better than cure. To avoid encountering the “This file type is not permitted for security reasons” error in the future, consider following these best practices:

Keep WordPress and plugins up to date

Regularly update WordPress core, themes, and plugins to ensure you have the latest security patches and compatibility improvements. Outdated versions are more prone to security vulnerabilities and may not support certain file types.
