I'm seeing the error
the theme directory "twentyfifteen" does not exist
for the twentyfifteen theme after trying a WordPress subdirectory install for the first time.
I can access the admin panel ok at
mysite.com/wp/wp-admin but the home page is blank (Not a WSOD 500 error but a 200 OK)
WP_DEBUG but can't find anything useful in the logs. WordPress version is 4.1
I also have wp-content in the document root directory. My file structure looks like this
|-- composer.json |-- composer.lock |-- index.html |-- index.php |-- vendor |-- wp |-- wp-config.php `-- wp-content
