I’m facing an issue when I try to migrate a Joomla installation to a different server. Let me first of all say I have copied all files from the old server to the new one, and migrated the Joomla database to a different server.
I’ve updated configuration.php to reflect the changes in the MySQL server.
When loading the site, it apparently works fine: connects to DB and allows all operations. However, when trying to access to the Joomla administration panel, and after successful login, an empty screen appears. There is no possible way to enter the backend.
