I have a development blog and a production blog, both have different databases but relatively the same files. I made some changes to the site theme and plugins on the development blog which I wanted to incorporate into the production blog. So I backed up the files of the production blog, and replaced the wp-config file from the development blog with the production blog's (in order to connect to the production database), and FTP'd in and uploaded the development blog files to the production blog's root. Shouldn't this be an easy way to transfer the site changes to the new database or am I missing something?
When i went to the site it was just a blank page. So I had to undo everything and put the old production site back up until i can figure out the issue.
