Attention Serious Fault. DataBase Account connects to another DataBase of diff

Attention Serious Failure DataBase Account..
I swapped my WHMCS 7.9.1 from one Account Dominio.site to Another Account Dominio.eu. I was surprised to realize that WHMCS has always been working with a database from the first domain, I forgot to change.

Finding out a while later when deleting databases on the first domain ... strange, never gave a domain error on whmcs 7.9.1.

That is the nature of MySQL.  It doesn't matter what account you connect from of you use the proper user/pass combo.  It is not tied to a home directory.

yep agreed not any issue though, you share the pass and user/db details and bam
