Please Help – Time Sensitive

I’ve been trying to export my development site to a live server and have had terrible luck doing so. I’ve done this 5 or 6 times before with no trouble, so I went searching through this forum for some help. I found these instructions from kriesi in an old post:

Hey!

You can use the undocumented export function for now that I use to create the settings for my dummy importer:

When in your admin backend (any page) simply append the this to the url ?avia_export, like: http://flyingstartonline.co.uk/fs/wp-admin/?avia_export

this generates a base64 encoded option set that you can simply copy and then save to the dummy.php file in includes/admin/dummy.php of your theme. then you either need to delete the dummy.xml file or create a wordpress XML export file rename it and replace it as well.

Not you have backed up your installation so that you could create a clone, simply by pressing the “import dummy data” button in your themes backend….

I’ve read through it a few times and I’m still a bit confused. Please please please can someone explain the process to me as though I were a complete imbecile (which I sometime am!)
