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

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?

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.

Re: Edit form is not displayed on panel admin

Got a same problem on version 2.3.2. 

But after command

bin/magento setup:di:compile

error changing to:

Fatal error: Uncaught Error: Class '[Vendor]\[Namespace]\Block\Adminhtml\Vendors\Edit\Form' not found in /var/www/html/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php:116
Stack trace: #0 /var/www/html/vendor/magento/framework/ObjectManager/Factory/Compiled.php(108): Magento\Framework\ObjectManager\Factory\AbstractFactory->createObject('[Vendor]\\[Namespace]\\B...', Array) 

Then command

bin/magento setup:upgrade

returns to the topic starter's exceptions
