git clone
cd MMM-next-episode
npm install

used the sample config from the readme
(typo missing : after password in the readme)

{
  module: "MMM-next-episode",
  position: "bottom_right",
  header: "Next-Episode",
  config: {
    id: '',
    hash_key: '',
    username: '',
    password: '',
    displaySeasonAndEpisode: false,
    displayShowingOn: false,
    displayEpisodeName: false,
    maxdays: 7,
    ShowThumbnail: true,
    ThumbnailSize: 'small',
    updateInterval: 180
  }
},

and see the qr code on the screen under the header

petek@MagicMirror-v2:/home/MagicMirror$ ls -la /home/MagicMirror/modules/MMM-next-episode/MMM-next-episode.js

yeah no /root/ that can create a loads of headaches like this.

the permissions are 3 sets of 3 rights

user read/write/execute
group anyone in this group
other anybody not specified above

the commands

are chmod which can set the individual
permissions using flags or a number
777 means all for all
770 mean user and group users can do anything, everyone else no access

the there is chgrp to change the group

all commands have help
–help

and most have a page in the manuals

man commandname

man chmod
man chgrp

you
eill need root permission to take root
permissions away

sudo gives root permission for this command

if you try to run as a normal user, you dont have permission to access them at all

thus the not found

No /root/

also, NEVER run this stuff as root…

is that the user you used when you installed the module???

ls -laF

do you find a folder with the proper name…

note the module name, the folder name AND the js file AND the register in the js file names MUST match exactly

[2025-08-21 19:25:57.758] [WARN] No /root/MagicMirror/modules/mmm-next-episode/mmm-next-episode.js found for module: mmm-next-episode.

/MMM-next-episode

magic mirror is case sensitive…

I think the module name is mmm-next-episode

[2025-08-21 19:19:45.691] [WARN] No /root/MagicMirror/modules/MMM-next-episode/MMM-next-episode.js found for module: MMM-next-episode.

But MMM-next-episode.js is present in the MMM-next-episode DIR

to do this

select the text you want to paste
in the message editor, paste the text, with a blank line before and after
then select the text you just pasted and press the </> button on the editor menu bar

this will keep the formatting and make long items (logs) scrollable…

I fixed the prior entries

//MMM-Next-Episode
{
  module: "MMM-next-episode",
  position: "bottom_right",
  header: "Next-Episode",
  config: {
    id: '',
    hash_key: '',
    username: 'myuser',
    password: 'mypass',
    displaySeasonAndEpisode: true,
    displayShowingOn: true,
    displayEpisodeName: true,
    maxdays: 7,
    ShowThumbnail: true,
    ThumbnailSize: 'small',
    updateInterval: 180
  }
},

//MMM-Next-Episode
{
  module: "MMM-next-episode",
  position: "bottom_right",
  header: "Next-Episode",
  config: {
    id: '',
    hash_key: '',
    username: 'myuser',
    password: 'mypass',
    displaySeasonAndEpisode: true,
    displayShowingOn: true,
    displayEpisodeName: true,
    maxdays: 7,
    ShowThumbnail: true,
    ThumbnailSize: 'small',
    updateInterval: 180
  }
},

MM version is v2.32.0

{
  module: "MMM-next-episode",
  position: "bottom_right",
  header: "Next-Episode",
  config: {
    id: '',
    hash_key: '',
    username:'your-next-episode-username',
    password: 'your-next-episode-password',
    displayShowingOn: true,
    displaySeasonAndEpisode: false,
    maxdays: 5,
    ShowThumbnail: true,
    ThumbnailSize: 'small',
    updateInterval: 180
  }
},

I just tested it on main branch and gave me the qr code after a pm2 restart
then the id and hash might appear as one long string but the first 9 numbers is your id and the rest is the hash.

verify that magic mirror is latest version.
