Hi,

Node-RED used to work until yesterday. Then it stopped.

I uninstalled Node-RED and Node.js, then reinstalled.

Here's how the Node-RED install went:  
c:\Users\ronen.perets\AppData\Roaming\npm\>npm install -g --unsafe-perm node-red  
npm WARN deprecated har-validator@5.1.5: this library is no longer supported  
npm WARN deprecated bcrypt@3.0.8: versions \< v5.0.0 do not handle NUL in passwords properly  
C:\Users\ronen.perets\AppData\Roaming\npm\node-red-pi -\> C:\Users\ronen.perets\AppData\Roaming\npm\node\_modules\node-red\bin\node-red-pi  
C:\Users\ronen.perets\AppData\Roaming\npm\node-red -\> C:\Users\ronen.perets\AppData\Roaming\npm\node\_modules\node-red\red.js

- node-red@1.1.3  
updated 1 package in 6.894s

When I start Node-RED and point the browser to localhost:1880, Node-RED shows in all its glory, HOWEVER no button works:  
Manage Pallete - Nothing happens  
Double click on node - Nothing happens  
Adding a Flow Tab - Nothing happens

When I try to add a node and deploy I get a message that deploy failed with config.forEach issue:

Also I get the following message on the browser console:  
red.min.js:16 Uncaught TypeError: $(...).size is not a function  
at o (red.min.js:16)

What version of node.js do you have?

Can you list the Node-RED startup log?

What version of Windows and what browser are you using?

That is different to the user you were logged in with when installing Node-RED:

> [@RonenPerets](#):
>
> c:\Users\ronen.perets\AppData\Roaming\npm\>npm install -g --unsafe-perm node-red

So you have done something odd to the setup since you would normally expect to see:

```auto
Settings file : \Users\ronen.perets\.node-red\settings.js

```

Note the extra backslash.

Thank you for your help.  
However the '' is there in the log, probably got deleted when copy&paste. It now shows:  
\Users\ronen.perets.node-red\settings.js

it seems it is seen as escape code for the '.' . It is there though.

You need to wrap that in back-ticks because Discourse is swallowing the backslash.

Starting to give up.  
I removed node-red, removed all folders related to it, removed node.js and npm and reinstalled all.  
Still same issue.  
Funny thing is that I have 3 custom nodes that I installed and uninstalled but they still show up in the palette even after uninstall and install of node-red

When you installed node-red globally, did you use an elevated command prompt?

You might try using my alternate installer or simply follow the same instructions to install node-red locally. That way you don't need to mess with admin rights.
