Fantasma saves your edits on its own as you work. This dialog opens when the project was saved from somewhere else while this window still had edits that were not saved yet. Saving them would overwrite the newer version, so this window stops saving until you reload. Fantasma first keeps those edits as a backup in the project's history. The dialog cannot be closed until you reload.
Check the basics first
Look for the project open somewhere else, such as another browser tab or window, another browser, another computer, or your phone. An AI agent you connected to Fantasma, such as Claude or ChatGPT, saves to the project too when it works on it. Finish your work in one of those places and close the others. A project that is only open in two tabs, with edits in just one, does not open the dialog.
Reload the latest version
Wait while the dialog shows "Saving a backup of your unsaved edits first…". Reload latest stays grayed out until the backup is saved.
Click Reload latest. The editor shows the project as it was last saved, from the other window or the agent.
The edits from this window are now only in the backup.
Get back the edits from this window
Fantasma saved them in the project's history as "Unsaved edits", with the time. Each conflict adds one.
In the reloaded window, click the sliders icon in the icon rail, Project settings.
Click History.
Click "Unsaved edits" in the list. It opens and lists the areas, such as templates or styles, where it differs from the project as it is now.
Restoring a version is part of Pro. On the Free plan, the list tells you which areas differ, not each change inside them, so you look through those areas and make your edits again by hand. Restoring the backup replaces what the other window saved, and Fantasma saves the other window's version to the history first, so neither is lost. Fantasma cannot merge the two, so to keep changes from both, restore one and make the other's changes again by hand. Restore an earlier version shows the steps.
The backup could not be saved
When the dialog says "Your unsaved edits could not be backed up yet, so they are not safe.", click Retry backup. Keep the tab open until the backup works.
If Manage history shows in the dialog, the project's history holds as many saved versions as it can. Click Manage history. In the history that opens, click the three dots next to a version you do not need, select Delete version, and confirm. Then close the history and click Retry backup.
If Retry backup keeps failing, check your internet connection and keep trying. Reloading the page with the browser's own reload button gets you out of the dialog, but the edits from this window are then lost.
Keep it from happening again
Edit a project in one window at a time, and reload a tab you left open before you edit in it again. When an AI agent works on the project, let it finish before you edit it yourself.

If the dialog keeps coming back with only one window open, contact us and send the project's name, a screenshot of the dialog, and the browsers and devices you use Fantasma on.
