Either your libxml was compiled with --disable-dom or your PHP installation is missing the DOM extension.
Thanks for the prompt response! Indeed, the DOM extension was not enabled. I added extension=dom to my php.ini and now it works.
Thanks again!
Hi, I’m having a similar problem that cropped up out of nowhere:
<br />

Do you have any idea what’s wrong?

Does this only happen with a specific page or are you experimenting with the API? i’m wondering because of the 'Body' argument to process_textnodes.
I’m not experimenting with anything. It happens with any page on my WP site as long as wp-typography is installed (regardless of whether or not it’s activated in the plugin listing).

That can’t be quite right. If wp-Typography were disabled, that code would not be executed. Could you describe your exact setup (OS, PHP version, HTTP server, singlesite/multisite etc.)? Also, could you try to expand the stack trace? It only goes back two levels, which does not reach the plugin code itself (only the embeded php-typography library).
From that stacktrace, $xpath->query( '/html/body' )->item( 0 ); returns null instead of a DOMNode object. That is weird because <body> tag is explicitly added around the parsed fragment, so that call should always return the outer-most <body> node that was added by the plugin.
That can’t be quite right. If wp-Typography were disabled, that code would not be executed.
I’d think so too, but that’s not what I’m observing.
I’m using Ubuntu 18.04 LTS, PHP 7.2, Apache 2.4.29, single-site.
How can I expand the stack trace? To get the trace I posted, I just added the following to to index.php:
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Try this Gist. It will log to an error file instead of displaying the errors on the frontend. The output should include the complete stack trace.

Please check your PHP ini files that extension=dom.so is not included twice. Also, the libxml extension is activated too, right?
I have now verified that extension=dom.so only appears once, and I have also added extension=libxml.so (which was not there before). I still get the same exception.
Also, the exception does not occur if the plugin is disabled. That simply seemed to be caused by caching; a few minutes after disabling the plugin, the site works.

Was there a time when wp-Typography worked correctly on your new server? Is the title of the page “Body”?
No, wp-typography never worked after the OS upgrade. Body is not the title of the page. Here’s the page (though all subpages also stop working if I enable wp-typography).

Have you got any idea where that Body comes from? It’s a string that’s processed as a title (the_title filter hook), might be from a widget or some other small part of the page, but I could not find it there.
Sorry, I have no idea. A quick grep -rnw '/path/to/relativisticramblings.com/' -e 'Body' did not turn up anything that I’d consider relevant. Perhaps it’s a string in the DB.
