I had a perfectly good Mushroom dashboard that I’ve been using for months. On my desktop, HA said I needed to reload my front end, but when I did, it completely broke my dashboard. Every mushroom card looks like this picture. However, it’s completely fine on the iOS companion app. No issues at all. I’ve restarted HA. I’ve hard refreshed my Chrome browser. Nothing works. I don’t even know why it happened, except that I reloaded. Any ideas here?
Try uninstalling Mushroom and reinstalling it. It will not affect your dashboard/layout.
As always, when testing fixes it’s best to create a backup and have it stored locally on a separate PC.
Ended up restoring from a backup from Google Drive and it’s back working again.
