Recently, I had to relocate the Invoiceplane database to another IP. I changed the hostname in application/config/database.php:
But it still throws a database error:
Unable to connect to your database server using the provided settings.
Line Number: 99
Invoiceplane and the database are on separate servers, but I can connect to the database from the Invoiceplane server.
How can I solve this? Changing the hostname doesn’t seem to work.
