Module MMM-pages not working after Upgrading to 2.38

p1lspeda

Hi,
I manually updated to 2,38 just now.
After re-installing all my modules and copying my cutom.css and config.js, my MagicMirror is playing up.
I use MMM-pages which seems to have stopped working.
This is my MMM-pages config

    {
                        module: "MMM-pages",
                        config: {
                                rotationTime: 1000 * 30,         // rotate every 30 seconds
                                modules:[
                                                ["MMM-MyCommute","MMM-CountDown","MMM-OpenWeatherForecast","clock","MMM-PublicTransportHafas","MMM-DWD-Pollen","MMM-Fuel"], // page 1
                                                ["MMM-CalendarExt3"], // page 2
                                        ],
                                fixed: [                         // modules that are always shown
                                        "MMM-Wallpaper",
                                        "updatenotification",
                                        "MMM-Cursor",
                                        "MMM-page-indicator",
                                        "newsfeed",
                                        ],
                                },
                },

The logfile does not really give me any clues:

Only workaround I have found is to disable MMM-CalendarExt3.
Disabling MMM-pages has no effect - same problem as if MMM-pages is enabled…
Any Idea what is happening ?

It all worked perfectly on 2.37

@p1lspeda I think you are using my fork of pages… they have changed the official one since then

but the wallpaper error is in the node_helper…

can you open the developers console

ctrl-shift-i (lower case letter eye)
select the console tab
and look around for any errors, top right would be a number of those as well (pink box)

@sdetweil
First of all: thanks for taking the time to help.
The MMM-pages module I am using is: https://github.com/edward-shen/MMM-pages
After disabling the MMM-pages module, the MMM-Wallpaper Error has vanished from my logfile.
I stated before I had disabled MMM-pages: this was incorrect, I had simply disabled page-2 within the MMM-pages config.

Weirdly my the MMM-PublicTransportHafas has also failed to work under 2.38.
It just shows up as “UNDEFINED” and no logfile entry.

@p1lspeda I think @kristjanesperanto has worked on both those modules recently

KristjanESPERANTO

@p1lspeda Could you share the first error shown in the browser console? Where exactly does Hafas display UNDEFINED, and is stationName set?

Which versions of MMM-pages, MMM-PublicTransportHafas and Node.js are you running?

Which MMM-Wallpaper module are you using: kolbyjack’s or jupadin’s?

Hi,
thanks to you too for taking the time to help.
Let me try and answer your questions.
According to the changelog, I am running version 1.5.1 of MMM-pages

## [1.5.1](https://github.com/edward-shen/MMM-pages/compare/v1.5.0...v1.5.1) (2026-08-12)

According to the changelog, I am runnung version 4.5.2 of MMM-PublicTransportHafas

## [4.5.2](https://github.com/KristjanESPERANTO/MMM-PublicTransportHafas/compare/v4.5.1...v4.5.2) (2026-08-31)

Node.js:
this is weird - the install.log from sam’s install/upgrade script states v. 22.22.2

Node currently installed. Checking version number.
Minimum Node version: v22.22.2
Installed Node version: v22.22.2
No Node.js upgrade necessary.

a nodejs -v shows something entirely different

pi@magicmirror:~ $ date
Fri  2 Oct 06:21:37 CEST 2026
pi@magicmirror:~ $ nodejs -v
v20.19.2

As for the MMM-Wallpaper: I am using kolbyjack’s version

stationName is set

...
stationID: "3029051",
stationName: "Höfchen/Listmann",   // Replace with your station name!
...

The UNDEFINED is shown on my screen

I think this is the first error I could find in the console browser

Edit:
I have updated nodejs to v24 and I have updated MMM-Wallpaper (I noticed kolbyjack had updated his git 3hrs ago).
My MagicMirror-error.log does not show any errors

/home/pi/MagicMirror/node_modules/electron/dist/electron exited with signal SIGINT
[2026-10-02 07:00:27.480] [WARN]  [apis] MMM-Fuel: Filtered stationIds list is empty

I have done some more debugging and I have 2 issues:
1st Issue is MMM-PublicTransportHafas: I have just updated to https://github.com/KristjanESPERANTO/MMM-PublicTransportHafas and the issue has been resolved.

2nd issue was with MMM-pages:
After starting MagicMirror, my mirror would switch directly to the 2nd page.
The automatic switching between page 0 and page 1 stopped working
Only after I had manually switched to my 2nd page (clicking on the indicator provided by MMM-pages-indicator), the automatic switch started working and my Mirror is almost back up and running.

It seems as if I have identified MMM-pages as the culprit.

KristjanESPERANTO

@p1lspeda Thanks for the update! Could you share your current MMM-pages config and the console messages from startup until you switch pages manually?

@KristjanESPERANTO
Here goes:
my MMM-pages config:

                {
                        module: "MMM-pages",
                        config: {
                                //rotationTime: 1000 * 30,         // rotate every 30 seconds
                                timings: {
                                                default: 30000,
                                                0: 30000,
                                        },
                                modules: [
                                                ["MMM-MyCommute","MMM-CountDown","MMM-OpenWeatherForecast","clock","MMM-PublicTransportHafas","MMM-DWD-Pollen","MMM-Fuel"], // page 1
                                                //["clock"],
                                                ["MMM-CalendarExt3"], // page 2
                                        ],
                                fixed: [                         // modules that are always shown
                                        "MMM-Wallpaper",
                                        "updatenotification",
                                        "MMM-Cursor",
                                        "MMM-page-indicator",
                                        "newsfeed"
                                        ],
                                },
                },

And while I was trying to get the info/errors from the console browser - as it always happens - my MagicMirror started up without any issues.
No idea what has changed - but it is working.
Btw: while I was writing this reply, I got an update notification for MMM-pages. I updated the module and everything seems to be working fine.

Thanks for your patience and help

                                            ["MMM-MyCommute","MMM-CountDown","MMM-OpenWeatherForecast","clock","MMM-PublicTransportHafas","MMM-DWD-Pollen","MMM-Fuel"], // page 1
                                            //["clock"],
                                            ["MMM-CalendarExt3"], // page 2

just for a side discussion, there is another way to config pages

using a page name like “page1” (you had this comment at the end // page 1)
and then adding the classes:“page1”, to all the modules you want on page1…

I always had trouble remembering where this module was when I was looking at its specific config, had to scroll back to pages config, lost where I was in config, then have to find it again… repeat too many times

and the page names can be anything
mom, dad, joey, mary, stocks, weather, whatever
i call the fixed section , “fixed”
then the page def looks clean

and the modules tell me where they are… never have to look back and forth , where was this again?

so your def would have been

{
                        module: "MMM-pages",
                        config: {
                                //rotationTime: 1000 * 30,         // rotate every 30 seconds
                                timings: {
                                                default: 30000,
                                                0: 30000,
                                        },
                                modules: [
                                                ["page1", 
                                                 "page2"
                                                ],
                                fixed: [ "fixed"  ]                       // modules that are always shown
                                },
                },

then on the def for MMM-CalendarExt3

                {
                      module:"MMM-Calendar-Ext3",
                      position: .....,
                      classes:"page2",
                      ...
                      config: {
                             ext3 config parms
                      } 
                }

if you want the same module on multiple pages, just add the space separated list of page names

                   classes:"page2 page5",  // in any order
