[Solved] openHab 3 UI suddenly shows "Overview not yet configured" and no click works

• Platform information:
  • Hardware: Raspberry Pi 4 Model B Rev 1.4 8 GB, external SSD
  • OS: Pi Os Buster latest version
  • Java Runtime Environment: openjdk version “11.0.9.1” 2020-11-04
  • openHAB version: 3.0.2 - Release Build

Hi,

my openHab UI stopped working all of a sudden.
I was working on a custom widget when the UI stopped reacting to my mouse clicks.
I waited for a while and then, after there was still no reaction, I reloaded the page.

But now my Overview page is gone, it’s just “Overview not yet configured”.

And still no reaction when I try to click anything, doesn’t matter if I click on “Settings”, “Developer Tools”, my Profile or anything else: Nothing happens.

I checked my jsondb folder and there I can see, that all my configurations and custom widgets are still there and correct.

The UI also shows my already configured pages, but here the same, if I click on them nothing happens.

The overview page and all other pages worked before.
Habpanel is still working and all things and items are still there.

What I have tried already:

• Reinstall openhab via openhabian-config
• Restart openhab
• Reboot system

Very strange, maybe someone can help me what to check or do next.

Thx,
Martin

Update:
When I try to use the url directly, e.g. …:8080/profile, I get “Not found”.
Also the other UIs, like CometVisu and Habpanel, are not shown on the right side, the sidepanel is just empty…

Try clearing your browser cache? I know Chrome especially caches aggressively

Thx, I tried, but that doesn’t help.
I also tried in Firefox, which I didn’t use at all for openhab 'til now, but it’s the same with it.

Sounds like you may have incorporated a fatal error into your widget definition which is causing the whole UI to fail to load. You probably need to restore one of the automatic uicomponents_ui_page.json backups in the userdata/jsondb/backup folder. If you think that will lose you too much work and you know where the error might be you can try to just edit the uicomponents_ui_page.json directly but don’t do that without reading the Editing the JSONDB, a last resort of the following post:

OH 3 Tips and Tricks

EDIT: Added more content to the editing the JSONDB section EDIT: Added the “Don’t Wait, Try it Out” section EDIT: Added autoupdate and persistence sections This is going to be a relatively sparse set of notes, tips and tricks, and other advice for setting up openHAB 3 through the UI. It will eventually be turned into a full tutorial and perhaps added as an addendum to the Getting Started Tutorial. But I don’t want to wait before getting some of these out in the open. It’s mostly just notes ri…

That’s a good advice, I will try that.
Right now I uninstalled openhab and I now reinstall it and restore it from backup.
If then the error still appears I will try your solution.

Hi JustinG,

@JustinG

You probably need to restore one of the automatic uicomponents_ui_page.json backups in the userdata/jsondb/backup folder.

You where right, that did the trick.
My custom widget was causing the complete UI to stop working.
These where my steps to get back to production again:

• Stoping openhab
• Clean cache
• Edit uicomponents_ui_widget.json and deleted the custom widget declaration from file
• Edit uicomponents_ui_page.json and deleted the widget from config
• Restart openhab

After that I created my custom widget again without the last changes and everything is working again.

Thx very much for your help
Martin
