Moving on by installing invoiceplane, there was a problem installing database.
Reading the log file, was due to "mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication"
With a little of workaround having not root access in your server, you can simply fix it going to your db dashboard (in my case phpmyadmin) excecuting this simple sql
SET PASSWORD = PASSWORD(‘yourPassword’)
I’m not quite sure yet but I would assume that it’s not recommended to use MySQL 4 anymore. I mean the current version is 5.7 and InvoicePlane requires at least version 5.
