Solution for : Error while deleting an image

Hi,

If the plugin is activated, when deleting an image, an error appears: Error in deleting the attachment.

The plugin was registering a delete_attachment hook that called a method webpc_remove_original() in the main class, but this method didn’t exist. This caused a 500 error when trying to delete an image.

Solution

Add the missing method webpc_remove_original($attachment_id) to the WEBPCbySheepFish class. This method simply calls the static method of the same name in the WebpC_Remover class.

Add method in webp-conversion.php (after webpc_remove_originals_selected) – Line 674 (just before function webpc_convert_single) :

<?php
/**
 * Hook callback for when an attachment is deleted.
 * Removes the backup/original file associated with the attachment.
 *
 * @param int $attachment_id The attachment ID being deleted.
 * @return void
 */
public function webpc_remove_original($attachment_id): void
{
    WebpC_Remover::webpc_remove_original($attachment_id);
}

Root Cause

Line 91 in webp-conversion.php registers the hook:

add_action('delete_attachment', [$this, 'webpc_remove_original']);

But the method webpc_remove_original() was not defined in the class, causing a fatal error when WordPress tries to delete an attachment.
