Just did a manual update to the latest version (1.32.1).
Of four sites running on that codebase, one and only one is now showing this error:
Class "FileStorageController" not found
Anyone have any ideas?

My guess is that it is Computed Field rather than Entity Plus; Entity Plus is used very widely across Backdrop as many popular modules have it as a dependency. I can't see any similar issues in the queue for that module but perhaps you had saved a field definition that was invalid PHP?

I seem to have traced this to a problem with entity_plus. Disabling computed_field and entity_plus (which were not actually being used) seems to have made the site available again.

Hi,
That error usually means the update didn’t fully replace or load all files. Check that all the core files were uploaded correctly — especially the controllers or classes directories. Sometimes the autoloader cache (like bootstrap/cache or similar) needs to be cleared after a manual update.
Also confirm your composer install (or composer dump-autoload) ran successfully if the system uses Composer. That usually resolves missing class issues like this.
To be very clear: Backdrop does NOT need composer and never will. While some use composer with Backdrop it is NOT required.
