Installing Pressbooks 4.0.0

I tried to upgrade my multi site installation of Wordpress to Pressbooks 4.0.0 but I’m getting an error which I’m not quite sure how to fix. Actually the autoload file of the composer as i can see, is included and it also exists.

I followed instructions on how to install the new update from here:

Any advice is appreciated.
Thank you!

Did you download the zip-File from the releases-page? It seems as if you just downloaded the git-files, but there some dependencies are missing.

Thank you for the reply!
I tried installing everything again from scratch but now it throws me this:

Fatal error: Uncaught Error: Class ‘PressbooksMix\Assets’ not found in /var/www/vhosts/ Stack trace: #0 /var/www/vhosts/ pressbooks_book_info_page(’’) #1 /var/www/vhosts/ WP_Hook->apply_filters(NULL, Array) #2 /var/www/vhosts/ WP_Hook->do_action(Array) #3 /var/www/vhosts/ do_action(‘wp_enqueue_scri…’) #4 /var/www/vhosts/ in /var/www/vhosts/ on line 32

Yes i downloaded everything from the releases :slight_smile:

Oh, I know what the issue is. Hang on.

Can you try again by downloading the new zip ( from here?
