Hi there, I am hosting a WordPress multisite with activated multinetwork. One o…f the networks has pressbooks. The main catalog never worked, so I tried out this plugin. But then I get this error (version 1.3.7). WordPress Version 6.7.1 • SQL 14 • PHPv 8.1.31 ``` [18-Jan-2025 21:20:33 UTC] PHP Fatal error: Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, class "PressbooksNetworkCatalog\PressbooksNetworkCatalog" not found in /var/www/html/wordpress/wp-includes/class-wp-hook.php:324 Stack trace: #0 /var/www/html/wordpress/wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters() #1 /var/www/html/wordpress/wp-includes/plugin.php(517): WP_Hook->do_action() #2 /var/www/html/wordpress/wp-settings.php(559): do_action() #3 /var/www/html/wordpress/wp-config.php(140): require_once('...') #4 /var/www/html/wordpress/wp-load.php(50): require_once('...') #5 /var/www/html/wordpress/wp-admin/admin.php(34): require_once('...') #6 /var/www/html/wordpress/wp-admin/network/admin.php(13): require_once('...') #7 /var/www/html/wordpress/wp-admin/network/plugins.php(11): require_once('...') #8 {main} thrown in /var/www/html/wordpress/wp-includes/class-wp-hook.php on line 324 ```
