a quibble with the instructions. They say:
Upload the whole /themeframe-css/ directory into the root directory
Better language would be
Upload the whole /themeframe-css/ folder (not just the contents) into the root directory
I'm about to discover the consequences of upload the contents (but not the folder) to root. Actually, I already know. When you go to the site, you get the TF login prompt, not the site.
UPDATE A FEW MINUTES LATER
If you repeat my dumb mistake and fail to upload the FOLDER, the contents upload will overwrite the WP default index.php with the TF index.php. Then, when you use your FTP client to create the TF folder and move the uploads into it (hint: they will all show the same date and time on which you did the upload so they are easy to recognize) into the newly created TF folder, you will have to go back to your local copy of WP index.php and reinstall it in root.
Once you do that, things will be normal. (phew!!)
