Hi @araiwaa,

First of all, please remove the closing PHP tag at the end of the snippet ?>. In PHP files, it’s best not to add that at the end of a file/snippet to avoid unwanted output.

Regarding the error you are running into, that is related to your code trying to access the ID property on the $post variable when that is not available. Due to the way you are loading the code as a shortcode, the ID is not available in that context so it is throwing an error on the line with this code: $tags = get_the_tags( $post->ID );

To get around this, I suggest adding a check above that line, something like this:
```
if (empty($post->ID) ) {
return '';
}
```
