Hello @Aveeva ,

I assume that, you have migrated the data, then try to setup the theme.

Please run following command:

php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento indexer:reindex
php bin/magento cache:flush
php bin/magento setup:static-content:deploy -f
chmod -R 777 var/ pub/ generated/

Also can you please share the link of images as this image will be visible only when approved by moderator.

[Binod Yadav]

Hello , 

Please enable the Error Reporting. In bootstrap.php, there is:

ini_set('display_errors', 1);

Run below commands

php bin/magento deploy:mode:set developer
php bin/magento cache:clean
php bin/magento cache:flush

@Binod Yadav  What is this error mean?

 main.DEBUG: cache_invalidate:

[Binod Yadav]

Hello @Aveeva ,

As per previously comment, your frontend area is showing blank page, so when you enable the error reporting, then you got actual error in frontend area.

Hello , 

Basically, when run the Settings  migration for migrates stores, websites, and system configuration like shipping, payment, tax settings, etc. Then your  theme327k  is moved on core_config_data.

bin/magento migrate:settings

Please connect you sql and check the theme value in core_config_data.

select from core_config_data where path = 'design/theme/theme_id'


NOTE :If possible, please send your server credential, you if can't run the sql query.
