Now My form does not display And in my system.log file I have this error

I activated the developer mode I have 2 exceptions

2 exception(s):
Exception #0 (Magento\Framework\Exception\LocalizedException): Invalid block type: Maxime\Jobs\Block\Adminhtml\Department\Edit\Form
Exception #1 (ReflectionException): Class Maxime\Jobs\Block\Adminhtml\Department\Edit\Form does not exist

 

How can I resolve this problem?

 

Thank you!

Re: Edit form is not displayed on panel admin

You have LocalizedException issue as per your error log.

 

So to resolved this issue , you need to remove your var/generation , var/cache directory from the root directory of application.

 

Now run the below commands :

 

 

php bin/magento setup:di:compile
php bin/magento cache:clean
php bin/magento cache:flush

Generally LocalizedException will occur when you have issue with controller and block file with factory class.
