Overview of the issue

Sometimes, you might encounter the following fatal error:

  • Fatal error: Uncaught exception ‘InvalidArgumentException’ with message ‘Argument ID must be numeric and greater than 0’

This issue is related to the WPML Media Translation plugin. It happens if you have an image that has no attachment data and is just an absolute link to the image.


This issue will be fixed in the future release. As a temporary workaround you can use the following steps.

  1. Edit the class-wpml-media-image-translate.php file found in the ../wpml-media-translation/classes/images-translation/ folder.
  2. Use the following code to replace the get_translated_image_by_url function.

public function get_translated_image_by_url( $img_src, $source_language, $target_language ){

$attachment_id = $this->get_attachment_image_from_guid($img_src, $source_language);
if (!$attachment_id) {
$attachment_id = $this->get_attachment_image_from_meta($img_src, $source_language);
if ($attachment_id){
$size = $this->get_image_size_from_url($img_src, $attachment_id);

return $this->get_translated_image($attachment_id, $target_language, $size);
} else {
return $img_src;

  1. I found the same issue.
    This workaround solves it but …. it is a dirty hack.

    Why an image would not have it’s attachment_id?

    Anyone with a more elegant solution?

  2. WPML Media is causing some of my websites not to upload files (PDFs or Images). It gives the red warning HTTP ERROR 500.

    Now for some reason, I cannot open a ticket anymore… You guys hid the CREATE NEW TICKET pretty well……..
