Everything on my site disappeared

I have a problem with Blank Sidebox Mod even so I follow all the instructions.

I think the problem is because when I make changes in Crimson Editor, I did not save with an extension name
I did not know this until after I upload everything to the server.

Even so I remove the bad files and replace with proper files with extension .php, the Admin still says "Missing" and in two instant show Box File Name of files without the extension.

I delete these files with Filezilla and also go into cPanel to search and delete them.
A file search in cPanel now only shows correct files in correct places but Admin does not update.

One box file name shows Red. The file name is sideboxes/barebones/ebook_sidebox.php - sideboxes/barebones/ is Red. When I turn this file on, I lose everything. When I turn it off, everything comes back.

There are two sideboxes/ebook_sidebox that have red highlight and the words MISSING - these files should be gone.

I have also loaded from last nights backup and re-added the sidebox files, but it is still the same.

(I only do this today so the backup is clean)

I think Admin should update when I have deleted the files. It still shows the old files.

The correct files should be:
includes/languages/english/extra_definitions/barebones/ebook_sidebox_defines.php
includes/modules/sideboxes/barebones/ebook_sidebox.php
includes/templates/barebones/sideboxes/tpl_ebook_sidebox.php

How can I update Admin to show me the correct files?

thank you
