Hello,  
I had to reinstall `influxdb` but unfortunately I forgot to update `node-red-contrib-influxdb` nodes so now I am not able to access to nodered UI.  
Looking at logs it tells:

```
at new RequestError (/data/node_modules/influx/lib/src/pool.js:52:28)

12 Feb 14:56:02 - [error] [influxdb out:3de57654.f35602] Error: A 401 Unauthorized error occurred: {"error":"authorization failed"}

```

So I tried to remove `node-red-contrib-influxdb` but now the logs tells:

```

```

and in the same way the UI is unaccessible:

Is there any way to fix this?

Missing nodes should not stop the ui from running. Have you tried refreshing the browser?

You should be able to reinstall them from the command line  
cd .node-red  
npm install

I was using firefox under Windows and I got the blank UI.  
Then I am using safari and all looks right... I had to better investigate the issue
