When you load a website in PageFabric, the workspace opens pages that belong to another recently used website.
The problem is caused by the workspace settings that messed up during your last work session.
- Close PageFabric
- Open your profile folder here: C:\Users\[USERNAME]\AppData\Local\PageFabric
- Select all the ".JSON" files that start with "ws_"
- Delete them
- Restart PageFabric
