The following themes are installed but incomplete. Themes must have a stylesheet and a template.
__MACOSX Stylesheet is missing.
Here's the content of the theme directory:
404.php gpl-3.0.txt page-blog.php readme.txt
README.md header.php page-componentsguide.php rtl.css
archive.php ico page-full-width.php screenshot.png
author.php img page-home.php search.php
comments.php includes page-jsguide.php sidebar-blog.php
css index.php page-scaffoldingguide.php sidebar.php
footer.php js page-styleguide.php single.php
functions.php lang page.php style.css
Any help would be appreciated.
You haven't got all the files. Download them from https://github.com/rachelbaker/bootstrapwp-Twitter-Bootstrap-for-WordPress
...and I'd rename the theme folder to bootstrapwp as well, you shouldn't be calling it __MACOSX.
