Have you ever tried uploading a file to your website, only to be blocked by the frustrating “File Type Not Permitted for Security Reasons” error? This common security restriction prevents potentially harmful files from being uploaded, but sometimes it blocks legitimate files too.

In this guide, we’ll explain why this error occurs, how to fix it safely, and best practices to maintain security while allowing necessary file types. Plus, we’ve included a video tutorial for easy troubleshooting! 🎥

Why Does This Error Occur?

Websites restrict certain file types to prevent security risks like:

Malware uploads (e.g., .exe, .php)

Script injections (e.g., .js, .html)

Server vulnerabilities from unsafe file formats

However, sometimes valid files (like .svg, .zip, or custom extensions) get blocked unnecessarily.

Benefits of Fixing This Issue

✅ Upload necessary files without restrictions

✅ Improve user experience for customers/clients

✅ Maintain security while allowing safe file types

✅ Avoid workarounds that could compromise your site

How to Fix “File Type Not Permitted for Security Reasons”

Method 1: Allow Additional File Types in WordPress

Install & activate the “File Upload Types” plugin

Go to Settings > File Upload Types

Add your desired file extensions (e.g., .svg, .psd)

Save changes and retry uploading

Method 2: Modify .htaccess (For Advanced Users)

Access your site via FTP/cPanel

Locate the .htaccess file in the root folder

Add this code (replace .zip with your file type):

apache

<FilesMatch "\.(zip)$">

  Order Allow,Deny

  Allow from all

</FilesMatch>

Save & re-upload the file

⚠️ Warning: Incorrect edits can break your site—backup first!

Method 3: Update PHP Configuration (For Developers)

Open php.ini (found in your hosting panel)

Locate upload_max_filesize and post_max_size

Increase limits if needed (e.g., upload_max_filesize = 64M)

Restart your server for changes to apply

Pro Tips to Stay Secure

🔒 Only allow necessary file types – Don’t enable risky extensions like .exe

🔒 Use security plugins (e.g., Wordfence) to scan uploads

🔒 Regularly audit allowed files to prevent abuse

Fixing the “File Type Not Permitted for Security Reasons” error is simple once you know how! Whether you use a plugin, edit .htaccess, or adjust PHP settings, always prioritize security while allowing the files you need.
