Hmm, ok, I learned how to install a plugin and unzipped the WP Campaign Monitor into /wordpress/wp-content/plugins/communications.
It now appears in the plugins admin page, and I can activate it. Now what? I don’t see any admin links that say anything that might relate to configuring this plugin or using it.
If I click on the name of the plugin in the plugins admin page, I get this 404 error:
Not Found
