I recently uploaded a new theme to my server and the documentation says to do the following:
Install
1.
Simply unpack the contents of the zip file into the /themes directory in your SilverStripe installation.
2.
Change to the theme by putting the following line in your ./mysite/_config.php:
SSViewer::set_theme("themename");
3.
Visit your homepage, ensuring you flush the cache (append ?flush=1 to the URL).
The problem I'm having is that I cannot find the _config.php file in ./mysite/
I'm using version 2.2.3. How do I switch the theme?
