The fatal was being thrown by the threewp-broadcast plugin, which references the MULTISITE constant without first checking for its existence. This triggers a fatal error in PHP 8+. I fixed this in the plugin itself soon after our PHP 8 migration, but the plugin has since been updated, overwriting my change.

We had the following line in our cac-env-config.php file:

//define( 'MULSITITE', true );

With great fear in my heart, I uncommented it. It appears that the site is continuing to work properly (multisite, mapped domains, etc). But I don't know why it was commented out in the first place, and it's possible that there will be some unintended consequences. I'm copying Ray and Jeremy here so that they're aware.

Marilyn, the site should be accessible now.

Reopening. Setting the 'MULTISITE' constant appears to have broken many things. See #22284.

I've rolled back the change and will see if there's some sort of workaround I can use for threewp-broadcast.

Hotfix applied in https://github.com/cuny-academic-commons/cac/commit/f4c83a996f11c94f9576904a989bc236f130870a and pushed to production.
