On PHP 7.3.18, following warning will be printed, and it'll be also written in a zip file.
<b>Warning</b>: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"? in <b>{the directory of wordpress}/wp-content/plugins/wordpress-to-hugo-exporter-1.9.0/includes/markdownify/Converter.php</b> on line <b>351</b><br />
Then a server will send it with content-type: text/html header, and the binary data will be shown as text on a browser.
This problem has been solved on newest markdownify.
So I updated markdownify, and stopped displaying all error and warnings.
