Cannot upload SVG files in WordPress When we upload the SVG file, we recieve the notification “Sorry, this file type is not permitted for security reasons.” To Resolve this issue, we need to add the below function in the functions.php files function cc_mime_types($mimes) { $mimes['svg'] = 'image/svg+xml'; return $mimes; } add_filter('upload_mimes', 'cc_mime_types'); This will resolve the issue.
