Hello All,
I think I found a workaround:
Go to the database and find the wp_blogs table.
You will see under “domain” that the plugin didn’t change the domain to the new one.
Try to change it manually and then login to your dashboard with the login and password from the site that you’re migrating/cloning
I’m using All-in-One WP Migration v. 4.3.
Hope this helps.
