Zend unable to resolve plugin "auth" in 3.2.1

[fweep]

I had a working ViMbAdmin installation (I forget which version, but it was new around Dec 2019). I just installed 3.2.1, following the upgrade instructions, and now I get this error trying to view the home page:

Fatal error: Uncaught Zend_Application_Bootstrap_Exception: Unable to resolve plugin "auth"; no corresponding plugin with that name in /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php:340 Stack trace: #0 /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php(392): Zend_Application_Bootstrap_BootstrapAbstract->getPluginResource('auth') #1 /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php(404): Zend_Application_Bootstrap_BootstrapAbstract->getPluginResources() #2 /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php(637): Zend_Application_Bootstrap_BootstrapAbstract->getPluginResourceNames() #3 /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php(598): Zend_Application_Bootstrap_Bootstr in /var/www/admin.example.com/vimbadmin/vendor/shardj/zf1-future/library/Zend/Application/Bootstrap/BootstrapAbstract.php on line 340

I ran composer and it looks ok:

$ composer install --prefer-dist --no-dev

Loading composer repositories with package information
Installing dependencies from lock file
Nothing to install or update
Generating autoload files

My PHP knowledge is limited, so I'm not sure what the right way to resolve this is.

I downgraded to 3.1.1 and my installation is working again.

Hi @fweep

I had no issues myself upgrading from a number of different versions.

Did you make the changes in application.ini as advised in these notes?

If yes, they maybe a diff between application.ini and application.ini.dist might show up other changes?

Thanks, that fixed it! I hadn't gone through the prior release notes.
