Uploaded file is not allowed for file type – Error

@rochellewalr

As default WordPress doesn’t allow svg file for security reasons.

In recent changes we changed the validation when checking file types using get_allowed_mime_types() the standard approach from Worpdress.

Can your try and add snippet below in your theme/functions.php file?

function svg_mime_types( $mimes ){
  $mimes['svg'] = 'image/svg+xml';
  return $mimes;
}
add_filter( 'upload_mimes', 'svg_mime_types' );
