* Hi [@cfm168](https://wordpress.org/support/users/cfm168/) – could you please
check for me if this error still occurs when you have no plugins activated on
the site?

* I can find these two warnings when visiting the attachment page for an SVG because
WordPress does not set their (full-size) dimensions in metadata.
* Unless you would prefer disabling all image attachment pages, you could try adding
a filter to set both SVG dimensions to `0`:
* ```wp-block-code
function svg_attachment_metadata_dimensions( $data ) { if ( ( ! isset( $data['width'] ) || ! isset( $data['height'] ) ) && isset( $data['sizes']['thumbnail']['mime-type'] ) && $data['sizes']['thumbnail']['mime-type'] === 'image/svg+xml' ) { $data['width'] = 0; $data['height'] = 0; } return $data;}add_filter( 'wp_get_attachment_metadata', 'svg_attachment_metadata_dimensions', 10, 1 );
```

* Hello, Thank you all.
* Surprisingly the errors disappeared after installing a popular cache plugin.
I will wait more days to see if it is a real.

* Hello,
* I have WP6.7.2. I try to get help from IA and get the following advise:
* This error typically occurs when a script tries to access an array key that doesn’t
exist. In your case, the “height” key is missing in the array being referenced
in the image.php file. Here’s how you can fix it:
* Check if the Key Exists: Before accessing the “height” key, ensure it exists
using the isset() function. For example:
php
* if (isset($array[‘height’])) {
$height = $array[‘height’];} else {$height = ‘
default_value’; // Provide a default value if needed}
* *Debug the Code: Look at the code in image.php around line 40. Identify where
the array is being populated and ensure the “height” key is being set correctly.
* *Update the Theme: If you’re using an outdated version of the Twenty Eleven theme,
update it to the latest version. Sometimes, these errors are resolved in newer
updates.
* I checked the line 40. Hope the author can test it and update the theme. Or some
one can help to create a related script for my Child theme as alternate solution.
* Thanks in advance!

* If you have a child theme, you have multiple options. The simplest might be wrapping
the `printf` in a condition like `if ( isset( $metadata['width'] ) && isset(
$metadata['height'] ) )`. That would skip adding the entry meta if the image
does not define width and/or height, so you might also want an `else` fallback.
* **Steps:**
1. Add Twenty Eleven’s `image.php` template in your child theme (if you have not
done that already).
2. Edit the `printf` code that begins after `$metadata = wp_get_attachment_metadata();`
with one of the code snippets below (or something else, as you like).
3. Save changes to the file, and upload it if you are not editing within the admin.
4. Visit the attachment pages for images, especially any pages you know had the
error messages.
* **Snippet 1**: Checks for width and height before outputting entry meta, and
shows only the date if it does not find both dimensions.
* ```wp-block-code
Published %2$s at %4$s × %5$s in %8$s', 'twentyeleven' ), esc_attr( get_the_time() ), get_the_date(), esc_url( wp_get_attachment_url() ), $metadata['width'], $metadata['height'], esc_url( get_permalink( $post->post_parent ) ), esc_attr( strip_tags( get_the_title( $post->post_parent ) ) ), get_the_title( $post->post_parent ) );else: printf( '%2$s', esc_attr( get_the_time() ), get_the_date() );endif;?>
```
* **Snippet 2**: Checks for width and height individually within the entry meta`
printf`, and gives fallback text if the dimension is not found. (The fallback
could be `'0'` or `'unknown'`, for example.)
* ```wp-block-code
Published %2$s at %4$s × %5$s in %8$s', 'twentyeleven' ), esc_attr( get_the_time() ), get_the_date(), esc_url( wp_get_attachment_url() ), isset( $metadata['width'] ) ? $metadata['width'] : '0', isset( $metadata['height'] ) ? $metadata['height'] : '0', esc_url( get_permalink( $post->post_parent ) ), esc_attr( strip_tags( get_the_title( $post->post_parent ) ) ), get_the_title( $post->post_parent ) );?>
```

* The fatal error in `image_get_intermediate_size()` is apparently a separate issue,
and you already opened multiple topics about that (the discussion should stay
on [one of those](https://wordpress.org/support/topic/fatal-error-4775/)). The
array key warnings appear when the image meta does not have the width or height,
but attachment 456 has both of those in the page before it stops on the critical
error.
* Redirecting the image attachment pages to the attachment itself should be the
quickest way to prevent both errors. Those pages often are not very valuable,
and you might benefit from removing them entirely. This is [possible without a plugin](https://make.wordpress.org/core/2023/10/16/changes-to-attachment-pages/)
since WordPress 6.4, but the All-in-One SEO plugin has the option under Search
Appearance > Image SEO.
* However, if you appreciate those pages and can fix the fatal error with something
else, this is another code snippet to try in a child theme or plugin for the
array key warnings (similar to the SVG-related filter above, without restricting
the image type).
* ```wp-block-code
function add_missing_attachment_metadata_dimensions( $data ) { // A value of 0 is not useful for visitors, but it could prevent errors. $data['width'] = isset( $data['width'] ) ? $data['width'] : 0; $data['height'] = isset( $data['height'] ) ? $data['height'] : 0; return $data;}add_filter( 'wp_get_attachment_metadata', 'add_missing_attachment_metadata_dimensions', 10, 1 );
