I have a very simple flow.

[{"id":"39737b3.0628584","type":"debug","z":"66472984.929868","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"false","x":850,"y":120,"wires":}]

I have copied a flow somewhere with "mraa-gpio-dout" in it, I did not have the node installed.

I deployed the flow without installing the node.

Subsequently I have installed the node but

Keeps telling me -  
Flows stopped due to missing node types.  
mraa-gpio-dout

I have deleted the flow as well and tried to start and send messages, but it keeps telling me "Flows stopped due to missing node types. mraa-gpio-dout" and "Error: node not deployed"

Try (on commandline):

```auto
node-red-stop
node-red --safe

```

It will start node-red in safe mode, remove the nodes that give the problems, deploy.

If that does not help tell us how you have installed node-red and what hardware and operating system it is running.  
Also post here the startup log that you see when starting node-red in a terminal. It should include the Welcome to node-red message.

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials  
file will not be recoverable, you will have to delete it and re-enter  
your credentials.

## You should set your own key using the 'credentialSecret' option in your settings file. Node-RED will then re-encrypt your credentials file using your chosen key the next time you deploy a change.

Hi,

This mraa-gpio-dout are back and causing trouble for me.

I have once again tried to node-red-stop and then node-red --safe then remove mraa-gpio-dout.

Any other advice?

```auto
node-red --safe 

```

Then remove the nodes from your flows first.

If you have not already done so, use the Search feature in node red to search for mraa.  
If that doesn't find anything then in a terminal in the .node-red folder run  
`npm remove node-red-node-intel-gpio`  
And post the result here. Then restart node red and see what happens.

I could not find it in the flow or node causing the trouble, also there were flow shown under "config" ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/5/15121a4085d906734523d366c99ba10e2fdf08d6.png)  
and not at the top of the flows ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/2/e23d8ff0ed10314fd1bc7385cd108e4df1c8441e.png) (I have subsequently delete them, you will only see the two now, I should have take screen shots to demonstrate prior of me deleting them)

I used Ctrl+f and searched for the nodes and flows that were not shown on the mail pallet and deleted them.

As you can see only the two flow I use now there and the rest deleted.

Think node-red got it self in a bit of a knot, as I have copied and pasted a lot of flow, experimenting on how thing work.
