Please use X_ITE from GitHub CDN:
<link rel="stylesheet" type="text/css" href="https://create3000.github.io/code/x_ite/latest/dist/x_ite.css"/>
<script type="text/javascript" src="https://create3000.github.io/code/x_ite/latest/dist/x_ite.min.js"></script>

code.create3000.de will be shutdown next year.
