I have set a test website up on the domain:
http://www.lastminutebarcelona.be . How do I copy this to the actual domain it
needs to be on when I am done?
Hey e-conomy!
In general this is not what we help with via support. If you are unsure about how to do that you can see this topic in the WordPress codex: http://codex.wordpress.org/Moving_WordPress
And use a plugin like this to extract your database: WP MIGRATE DB
Cheers!
