Nothing happens

Just downloaded the latest version, installed, set configuration to block all users except admin, set timer, set logo, set all fields, saved, went to different browser, and nothing. Just the site running as normal.

The problem is, I need this plugin to work immediately, so while I’m interested in hearing about your troubleshooting suggestions, it will be far too late by then.
