Dave, sorry to re-open this thread (felt like the right thing to do).

I have just updated a machine on V1.0.6 dashboard from 2.16.x to latest (2.22.1) and I get a very similar issue (restarted node-red, even restarted the server)...

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/6/1/611054cd121f4885729485957c9900adfd634d9b.png)

Was this ever resolved? Is there a quick fix?

PS: Settings file is almost bog standard (no theme set)

#### EDIT more info...

NR Version 1.0.6, node v10.15.3.

- Deleted settings & let it re-create - **same issue**
- Deleted all flows (renamed file) restarted - imported original flows - **same issue**
- Deleted all flows - restarted - added a single button - **OK**
- Added a ui\_table (V) - **problem is back**
- Removed ui\_table (leaving the button) and deployed - get no dashboard (only the "Welcome to the Node-RED Dashboard")
- Restart node-red - back to showing the button only

Seems to be an issue with ui\_table?
