Dear Alexandria Book Library Team,
I have installed abook 3.1.5 on my local development server, under Joomla4.0.2, with PHP 8, Linux Debian 10.
Joomla4 said that abook was installed, and "Alexandria Book Library" appears in the list of Components, with its sub-components. However, I cannot get any sub-components to open. They respond "An error has occurred. 500 behavior::tabstate not found"
My abook.php is the new version, with $controller->execute(JFactory::getApplication()->input->get('task'));
If this will be resolved in a later release of abook, then I can wait.
Richard.
Abook is no ready for joomla4 yet.
I'm working on it. I do not know the date of its release
