I've tried the Wordpress forum and Google searching to no avail, so I'm coming here as my last, best hope.
I'm using Wordpress (one-click, Advanced mode) on my site, www.touchwoodproject.com. I need to redesign it using a new theme but I need to change a bunch of posts, add some plugins, etc, so I can't use plugins like Theme Test Drive because that just changes the look of the site but nothing else. I don't want to take down my existing site while I make all these changes, so. How can I do this?
All the info I've seen (including using a plugin called Dev and Staging Environment) has you doing things like modifying the config file, but they don't exactly specify how and I have no idea how I'd "ensure it has read and write privileges in the Wordpress root". What?? I almost never use FTP and have no clue how PHP works or even what it really is.
Can anyone tell me a Dummies Guide to setting up a staging site so I can rework my site? Ever hopeful...
