Hello @NavinMdr 

It looks like, you haven't installed Mageplaza_Smtp extension properly.

Error is coming from this third party extension only - Mageplaza_Smtp

So kindly remove this extension and run the necessary command and check - error will not showcase to you !

hope it helps !

Hello Manthan Dave,

I already configured in Mageplaza_Smtp in my module list. I try to fix so many ways but not worked.

Hello @NavinMdr 

This localized exception only occurs when you have factory classes and other depended classes are not found in the module !

Try to run below command after installing extension and then check !

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean
php bin/magento cache:flush

Then check - here di:compile - must need to run - due to having a localized exception issue !

Hi Manthan Dave,

I used  php bin/magento setup:di:compile

I got new error blow:

Repositories code generation... 1/7 [====>-----------------------]  14% < 1 sec 56.0 MiBPHP Fatal error:  Class 'Hybrid_Provider_Model_OAuth2' not found in /var/www/html/app/code/Sm/SocialLogin/Model/Providers/Instagram.php on line 9

I am not using Instagram my site but showing error.

Hello @NavinMdr 

Yes, so now here is the valid reason you are facing error from MagePlaza_SMTP extension

Because your compilation process is not completing and due to that Factory classes of MagePlaza_SMTP is not creating and that's the reason its showing error.

If you are not using Instagram module/functionality - kindly remove that module and then run the given commands 

From that app/code directory - remove this - Sm_SocialLogin module 

Then run the above given command and it will resolve your error !

Hope it helps !

Hi @NavinMdr ,

Open view/adminhtml/templates/system/config/host.phtml and modify following line:

/** @var \Mageplaza\Smtp\Block\Adminhtml\System\Config\Provider $block */

to

/** @var \Mageplaza\Smtp\Block\Adminhtml\System\Config\Host $block */
