Reset Site Designer preferences
If Site Designer is crashing on startup, panels are not opening, the interface is stuck in an unexpected state, or preferences from a previous installation are causing conflicts, resetting preferences to factory defaults often fixes the problem.
When to reset preferences
Consider a preferences reset when:
- Site Designer crashes on startup (before any project is loaded).
- A panel or pane does not open or is permanently stuck.
- The app behaves correctly after a reinstall but breaks again shortly after — this often indicates a corrupted preferences file.
- You’re working through a support ticket and the support team asks you to reset.
What resetting does — and doesn’t — affect
| Affected (will be reset) | Not affected (safe) |
|---|---|
| Panel layout and positions | Your project .rsd files |
| Default export directory | Your exported HTML files |
| FTP credentials | Your assets and resources |
| Autosave interval setting | Your fonts and images |
| UI theme (light/dark) | Your license (re-enters on next launch) |
| CoffeeCup account login | Your content |
Windows: reset preferences
-
Close Site Designer completely
Make sure Site Designer is not running. Check the system tray and Task Manager to confirm.
-
Navigate to the preferences folder
Press Windows + R and type:
%APPDATA%\CoffeeCup Software\Site DesignerPress Enter.
-
Rename or delete the preferences file
In the folder that opens, find the preferences file (typically named
preferences.jsonor similar). Rename it (e.g., add.bakto the end) rather than deleting it outright — this preserves the old file in case you need to restore it. -
Relaunch Site Designer
Open Site Designer. It will create a fresh preferences file with factory defaults on startup. Enter your license key when prompted.
macOS: reset preferences
-
Close Site Designer completely
Quit Site Designer (⌘Q). Check Activity Monitor to ensure no background process is running.
-
Delete the preferences file
Open Terminal and run:
mv ~/Library/Preferences/com.coffeecup.sitedesigner.plist \ ~/Library/Preferences/com.coffeecup.sitedesigner.plist.bakOr navigate in Finder to
~/Library/Preferences/and rename the file manually. -
Clear the preferences cache
macOS caches preference files. Clear the cache by running in Terminal:
killall cfprefsd -
Relaunch Site Designer
Open Site Designer. It will regenerate the preferences file with defaults and prompt you to activate your license.
If a reset doesn’t fix the problem
A preferences reset resolves issues caused by corrupted settings. If the problem persists after a reset:
- Try a full reinstall: uninstall Site Designer, download the latest installer from coffeecup.com, and reinstall.
- Check if the issue is project-specific (create a new blank project — if it works, the problem is in the project file, not the preferences).
- Contact CoffeeCup support at coffeecup.com/help with the details covered in Reporting a bug.
