Server Errors all over the place

Hello!
I’m trying to install a child theme for twentytwelve and I’ve done the following steps and I receive this error:
Server error
The website encountered an error while retrieving https://marsmarineac.com/here/wp-admin/themes.php? action=activate&template=twentytwelve&stylesheet=childoftwentytwelve&_wpnonce=57cd8a101a. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

Here are the steps I’ve taken:
1. downloaded a copy of WP 3.5.1 to a directory on the site called here
2. downloaded another copy of WP 3.5.1 to my mac in the applications folder
3. in the themes folder, copied the twentytwelve folder and called it childoftwentytwelve
4. deleted the style.css file
5. created another style.css file and wrote this in it:
/*
Theme Name: Child of Twenty Twelve
Description: Child theme created for (xx)
Author: (xx)
Version: 0.0.1
Template: twentytwelve
*/

6. Compressed the folder and uploaded it to the folder called here
7. When I try to activate the theme called child of.., I get the message above
8. Further, when I return to Bluehost and try to get back to the WP admin at SimpleScripts, I get this message:
The website encountered an error while retrieving https://marsmarineac.com/here/. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request.

I have been working on customizing several themes and have had no problems activating my child themes at this stage before. Can anyone tell me what’s happening and how to fix it? I tried deleting all the files and reinstalling WP both to my machine and to the here folder, but every time I try to activate the child theme, I get the same thing.
