問題の再現ができませんでした。このプラグインの機能だとハイライト部分に行番号（添付画像の"5"）は本来でないと思うので、CSSまたはスクリプトの読み込みがおかしくなっているかもしれません。何かカスタマイズしていませんか？

I realized that this issue is caused by the long line (line 8) below it, full-width characters are fine here.
Yes, I use customized prism.css & prism.js, so I think this is a plugin issue.
Thank you for kindly reply.

By the way, when I click [Save Settings] in setting page, the url is redirected to
xxx/wp-admin/options.php without any trailing parameter, which lead to the following error.
So I can not change any setting value, any idea of this?
