Hello
Today I saw you how to upload svg file to wordpress website.
Have you ever encountered the “Sorry, this file type is not permitted for security reasons” error? Even though this is a common error message, it can sometimes be annoying. But you need not worry; while this message may appear inauspicious, it only signifies that WordPress does not support the file type you attempted to upload.
1. What Triggers ‘Sorry, This File Type Is Not Permitted for Security Reasons’?
For security concerns, WordPress restricts the file types you can upload through your site’s admin – photos, videos, documents, and audio. If you’re trying to upload a file not supported by WordPress, you are bound to get this error.

If you only upload file types that WordPress supports, you probably won’t come across the error message. Next, let’s have a look at what those file types are.
2 File Types Allowed in WordPress
WordPress enforces limitations on the file types you can upload for security reasons. By default, the file types you can upload are as follows:
Images: .png, .gif, .jpg, .jpeg, .ico, .bmp, .tiff, .webp, .heic.
Documents: .pdf, .doc, .docx, .xls, .xlsx, .ppt, .pptx, .pps, .ppsx, .odt, .PSD
Audio: .wav, .mp3, .m4a, .m4b, .aac, , .ra, .ram, .ogg, .oga, .flac, .mid, .midi, .wma, .wax, .mka
Video: .mp4, .m4v, .mpg, .mov, .wm, .wmx, .wmv, .avi, .mkv, .webm, .mpeg, .mpe, .flv, .divx, .ogv, .3gp, .3gpp, .3g2, .3gp2
These are all the most common file types. Any file that is not one of the permitted file types cannot be uploaded to the media library. You’ll get the “Sorry, this file type is not permitted for security reasons” error in WordPress when you try to upload them.
Now let’s take a look at how to fix this error message.
3 How to Fix ‘Sorry, This File Type Is Not Permitted for Security Reasons’
3.1 Check and Correct the File Type Extension Spelling
Check the extension of the file you’re trying to upload before making any changes to your WordPress settings or files. It’s possible that when you saved the file, you altered the extension unintentionally.
When you get this error, the first thing you should do is double-check that the file extension is correct. While editing or saving a file on your computer, you may accidentally erase or mistype a file name extension. So you need to check and correct the file type extension spelling and then upload the file.
3.2 Edit the wp-config.php File to Upload Any File Type
To upload all types of file extensions on your site, you can edit your wp-config.php file and add a one-liner code.
We recommend you always make a backup of your wp-config.php file before modifying it. Even a minor file issue can turn your site inaccessible. Once you’ve made a copy of your wp-config.php file, follow the instructions below to allow any file type upload.
You can access your wp-config.php file via FTP and look for the file in your site’s root directory. Click on View/Edit to open the file
Scroll down to the bottom of the file, and you’ll notice the line /* That’s all, stop editing! Happy blogging. */. Before this line, paste the following one-liner code:
define('ALLOW_UNFILTERED_UPLOADS', true);
Once you’ve added the code, save the changes, re-upload the file, and now you’ll be able to upload the new file types on your site.
This is a simple approach; however, it isn’t ideal for every website. You may want to specify which file types are allowed if multiple users upload files to your WordPress site. In such a case, you can edit the functions.php file and upload only certain file types.
3.3 Edit the functions.php File to Upload Any File Type
If you are code-savvy, you can add the upload_mimes filter to the theme’s functions.php file. This method will allow certain file types so that you have control over what’s uploaded to your site and prevent file upload vulnerabilities.
Once you’ve backed up your site, access your functions.php file via FTP. You can locate the file in your theme’s folder in the wp-content directory: Right-click and select View/Edit as shown below.
Add the following code snippet in the functions.php file from the theme files. The below code allows SVG and SVGZ files. You can modify the code depending on the type of file you want to upload.
/**
* Function to change the allowed mime types
*
* @param mixed $mimes Allowed mime types.
* @return mixed $mimes Updated mime types list.
*/
function my_custom_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' );
Once you’ve added the above code, don’t forget to save your changes. Beginners may have difficulty adding code to their functions.php or wp-config.php files. You can then utilize a WordPress plugin to allow new file types in WordPress.
3.4 Allow New File Types By Using a Plugin (This is my favourite. I used this way in many websites.)
Various plugins are available that allow uploading the file types to your site, such as the File Uploads Type plugin. At first, install and activate the File Uploads Type plugin from your WordPress dashboard.
There are two ways to permit uploads for a specific MIME type. The first is to select the box corresponding to the desired MIME type. However, if your desired type is not listed, you can add your custom file type at the bottom of the page. Click on the Save Settings button to save your changes.
You’ll now be able to add your file type without receiving an error message.
3.5 Change the Multisite Network Settings
You can easily add more file types if you’re running a multisite installation. To do so, navigate to Settings > Network Settings from your WordPress dashboard. Scroll down to Upload Settings, and you can add the extension for the file type in the input field next to Upload file types, as shown below.
Click on Save Changes once you’ve added your file types.
3.6 Secure the WordPress File Uploads
Allowing users to upload files in various formats may be easy, but it also leads to security concerns. You can make your site more secure while still allowing specific upload types. To do so, you should:
Limit the types of files uploaded to only those truly necessary.
Limit the file size that can be uploaded.
Use a WordPress security plugin to keep an eye on your site for flaws.
Scan your WordPress site for possibly malicious code regularly.
Non-registered users should be limited to only uploading the file types that they require. A file upload form is an ideal way to do this.
3.7 Contact Your Hosting Provider
If you’ve tried all of the methods above but still receive an error message, contact your WordPress hosting provider’s support team and explain your situation.
Your provider likely imposes stronger file-type restrictions than WordPress does by default. If the instructions above fail to resolve the ‘sorry, this file type is not permitted for security reasons’ error, contact your provider’s customer support.
