RapidWeaver 7 uses a new system to preview pages locally - basically, a local server is created. What we've recently found is that if your host's file has been tampered with (by a filter, security app, or similar), this would hinder RapidWeaver 7 from running/showing the local server. In return, the preview function would be rendered useless in RapidWeaver.
Try the following to see if your hosts file is as it should be. If it isn't follow necessary steps further down the page to repair it.
- Go to Terminal.app in /Applications/Utilities
- Type in sudo nano /etc/hosts
- Press the Enter key
- Enter your password (admin)
- Send a screenshot of what appears.
