Dashboard not working in IE11


I am able to get the Dashboard to work in Chrome and Firefox but it is not working in IE11. I searched online and it looks like the addition of a meta tag to the editor/templates/index.mst should fix this. I checked mine and I have that line in my file.

This is from my index.mst:

<!DOCTYPE html>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=0"/>
<meta name="apple-mobile-web-app-capable" content="yes">
<meta name="mobile-web-app-capable" content="yes">

Any suggestions?


I think it's the IE11 Object.assign issue here - https://github.com/node-red/node-red-dashboard/issues/402
currently fixed in master - not yet on npm.


Thanks dceejay. I downloaded from master and installed the missing modules since it is a new install. It did not solve the IE issue but I am now on v.0.19.4 now so that is a plus. :slight_smile:


Which version of dashboard does the node-red log report ?
What errors (if any) are you getting in the browser console log ?
Have you refreshed/reloaded the browser a couple of times to clear out the cache ?


Sorry for the late response on this, you replied back very quick, thank you. Good question on the browser console log. Any suggestions from seeing that log output?

node-red log shows it is starting up with v.0.19.4:

Yeah. That isn't the version of dashboard from master that has the fix. Should be 2.9.9-beta


That is from the source of Node-RED - which is not the dashboard. So when you say you downloaded from master, which repo are you referring to?

This is an issue with node-red-dashboard and has been fixed in node-red-dashboard's git repo as 2.9.9-beta


Got it working with node-red-dashboard 2.9.9-beta.

Sorry, I am a bit new to this but I am setting up some really awesome stuff with this. :slight_smile:


Let's hope you can move beyond IE11 - after all, that is a rapidly dying browser. Lots of websites have already stopped working with IE11.
