check_postgres documentation webpage not displaying.

Thank you for the wonderful tool. Definitely a swiss army knife of PostgreSQL tools.

I needed to check the documentation for check_postgres.pl and I clicked on the link https://bucardo.org/check_postgres/check_postgres.pl.html from the main check_postgres webpage and I ended up at a blank webpage, I am using Firefox, though I got the same behavior with Chrome, Brave, and Opera. A <ctrl/U> does show me the HTML which is quite large and looks like it should give you a webpage, but for some reason it does not display anything.

I even tried copying the check_postgres.pl.html file contained within the check_postgres-2.26.0.tar.gz to my workstation and tried viewing that. It also shows a blank webpage, again a <ctrl/u> shows me a lot of HTML code.

I tried viewing the check_postgres.pl.html file from 2.25 and it displays as expected.
