The fact that this error is not visible on your local server or that no one wrote about it yet does not mean that it does not exist.
I showed screenshots – there is an error.
I myself have not written about this for 2 years.
I am using a clean WP installation with Avada theme and W3 Total Cache plugin.
There are no modifications.
But in code visible this 1 download:
<?php printf( _n( '1 download', '%d downloads', $dlm_download->get_download_count(), 'download-monitor' ), $dlm_download->get_download_count() ) ?>
I don’t know why ‘1 download’ is used here.
But in some cases, as in mine … instead of the actual number of downloads, this code writes ‘1 download’
