Once I installed it, I went to it’s settings page, to be greeted with a page that said “Main settings” and nothing else.

Figuring file permissions were messed up, I started looking around. After finding that wp-content and wp-config.php were supposed to be writable, I took care of it, and I still had the same problem.

After looking around on the web, I found that if run on Windows, a few special steps were required.

With WP-Cache 2.1.2, the following steps worked for me (the original steps can be found here).

1. wp-config.php and wp-content should be writable by your web server
2. Copy wp-content/plugins/wp-cache/wp-cache-phase1.php to wp-content/advanced-cache.php
3. Replace wp-content/plugins/wp-cache/wp-cache.php with wp-cache.php (248)

In the referenced version, I performed the edits indicated here. It seems like the ob_end_clean() issue was fixed in the latest release of WP-Cache.
