If you but upload file types that WordPress supports, you probably won't e'er encounter this error message. Adjacent, let'southward review what those file types are.

Instead, opt for a video hosting service to shop your videos.

These file types are all quite mutual. However, you may desire to upload a file blazon that'due south non on this list. Or, y'all may exist trying to upload one of these permitted file types and still get the "deplorable, this file blazon is not permitted for security reasons" error message.

In either case, there are steps you lot tin can accept to avoid this error message.

In the example below, I tried to upload a .jpg file every bit an .avi file and got the mistake message equally a result.

This is an easy first step: If the file name extension is wrong, and then y'all can fix it and upload the file in the correct format. If information technology is correct, motion on to the next pace.

2. Change your multisite network settings.

If you are running a multisite installation — a network of sites that all share the same WordPress installation cadre files — then you tin easily add more allowed file types.

To add a file type, click Settings > Network Settings in your dashboard, then curl down to Upload Settings. In the input field adjacent to Upload file types, add the extension for the file type yous want to upload. And then, save your changes.

Users on any site in your network will now be permitted to upload all the file types listed here.

If you are running a single-site WordPress installation, you won't have this option in your settings. You'll need to effort i of the steps beneath.

iii. Edit your wp-config.php file to upload any file type.

If yous want to allow any and all file types to be uploaded to your site, y'all but demand to add 1 line of lawmaking to your wp-config.php file.

It'due south relatively unproblematic to do this, simply equally a all-time practice, you lot should always make a backup of your wp-config.php file before editing. Fifty-fifty a small error in the file can brand your site inaccessible.

In one case you've made a copy of your wp-config.php file, follow the steps below to permit any file type upload.

• At the end of the file, you'll encounter the line: /* That'south all, stop editing! Happy blogging. */. Above this line, paste the following code:

                                          
ascertain('ALLOW_UNFILTERED_UPLOADS', true);

This is a relatively easy solution, just not ideal for every website. If multiple users are uploading files on your WordPress site, for example, you may want to specify which file types are permitted. In that case, keep reading.

4. Edit your theme's functions.php file to alter permitted file types.

If you want to allow only certain file types to be uploaded to your site, you can employ the Upload_Mimes Filter. Hither's how:

• Access File Director via your hosting control panel.

function cc_mime_types($mimes) {
                      
    // New allowed mime types.
                      
  $mimes['svg'] = 'image/svg+xml';
                      
  $mimes['svgz'] = 'image/svg+xml';
                      
  return $mimes;
                      
}
                      
add_filter( 'upload_mimes', 'my_custom_mime_types' );
                                      

Annotation that the code to a higher place allows SVG and SVGZ files. You can change or add MIME types to this code snippet depending on what file types you want to upload.

While advanced users won't accept a problem adding lawmaking to their functions.php or wp-config.php files, beginners might. In that case, y'all can use a WordPress plugin equally well.

v. Install a plugin to add together more permitted file types.

If you'd prefer not to edit your wp-config.php or functions.php files directly, then you can use a plugin to add permitted file types on your website.

WP Add together Mime Types and File Upload Types by WPForms are 2 such plugins. While both are free from the official WordPress directory and highly rated, the File Upload Types plugin is more beginner-friendly. Follow these steps to use information technology:

In that case, the steps in a higher place won't resolve the "sorry, this file type is not permitted for security reasons" error, but your provider'southward customer support likely can.

Securing Your File Uploads

WordPress restricts the file types you can upload because allowing any file type would make it easier for bots and hackers to place malware on your site.

That'due south why we recommend specifying which file types you want to allow as to not open up your website to whatsoever type of file, and consider preventing users with lower roles from uploading files to your site.

Additionally, just upload plugin and theme files downloaded from legitimate sources, as these files are some of the most common causes of compromised WordPress sites. And, behave regular malware scans for harmful code that may have found its fashion in via an upload.
