Installing and upgrading help

Let me try and be clear. You should not use xampp for a production Moodle.

I can't think of a nice way to put this so you must excuse my bluntness - if you don't have the skills to create a Moodle site using 'standard' web server software then you probably don't have the skills to properly secure the site and perform backups etc.. None of this is rocket science and there are plenty of resources that can help you but you will need to learn a bit about being a server admin.

Yes, using a one click solution is easier and so is using a desktop Linux rather than a server edition but for a production site it isn't suitable.
