This might help.
www.ostraining.com/blog/wordpress/move-your-wordpress-site/ Where people get hung up with this is after changing the name of the site according to these directions, they can't figure out how to change it back. The simple answer is to not use the original data base, use a copy, so you can switch back to the original after you're done making the copy.
There are a lot of ways to accomplish this. This is only one way. I'll give you a couple of suggestions since we're coming into the weekend we might not be around.
Try using EZPZ backup - See number 8 in this newsletter article
www.ostraining.com/blog/wordpress/9-esse...l-wordpress-plugins/ Also another simple method is to install wordpress directly on your local machine and get a generic copy working.
Go to your original and go to the Dashboard > Tools and choose to export everything.
Then go to your working local site Dashboard > Tools and choose to import everything.
Copy over any template changes and make sure all plugins are installed and activated. That should also give you a duplicate site.
Another option is to simply copy everything over and use phpmyadmin to go in and change the url's directly in the data base tables. I think that might be too confusing though, so I wouldn't do it unless you're an expert.
If you run into problems, go ahead and post in the forum. No guarantees, but most of us try to check in on the weekends as well and we might pick up your post. Otherwise, we'll work it out on Monday for you.
Let us know the results.
Cheers,
