Whatever name i have tried all the names for new database and users , it says already exists. But there are no any database or users. This is still a fresh hosting.
Try adding a database for example like this:
Database Name: nursejamieapp_db
Database User: nursejamieapp_dbuser
It should work 🙂 ?!
On shared hosting you have to use unique database name 🙂 because someone is using that name but you can't see it . So you just have to come up with a unique name 🙂
Mark it as solved or leave a Kudos if this solves your problem )
