Background image cannot be changed

[johannes1984]

Using version 2.4.11 I cannot change the background image. I open the dialogue to chose the new file, select a jpg and then hit the "Save" button. Then it brings me back to the settings overview, confirms "You have successfully edited this setting" but still states "- not set -". And the background remains the standard image.

Same.

I hvae had this issue for so long that I just upload it via FTP manually and rename it to the default image name, works for me, I don't change it often enough for that to be too cumbersome.

Did you see the notes in the README at https://github.com/linuxserver/Heimdall#installing or https://github.com/linuxserver/Heimdall#new-background-image-not-being-set? For me bumping the max upload size fixed this.

What's unclear to me is why this isn't a default setting in the docker containers. I would have expected an 8 or 16MB limit would cover most images.

Because it's the php default, same as a bare metal install. And we make it user customizable in the container

Thanks. I filed linuxserver/docker-heimdall#100 because we don't know if the original reporter is using Docker or not.

Just to confirm that I use the Docker version

@aptalca I just encountered that changing upload_max_filesize only is not working anymore. Now I also have to set post_max_size. Maybe you could change the docs according?

I am still having this issue, despite setting my upload_max_filesize and post_max_size to 30M.

Depending on your connection speed, max_input_time and max_execution_time may also have to be raised.

I have tried setting upload_max_filesize post_max_size, max_input_time, and max_execution_time, and am unable to set a new background image

[rubenixnagios]

same on linuxserver/heimdall version 2.4.13, will try to rollback to a previous version just to check...
anyone found a fix for that?

[HannesJo0139]

I cannot reproduce. Are you using a proxy? It would need the same settings I think.

my bad sorry; just a permissions issue! background changed succesfully

Taking it off the proxy and tweaking upload_max_filesize and post_max_size fixed the issue for me.

Running - Docker > [lscr.io/linuxserver/heimdall:latest]
Set the config file php-local.ini with upload_max_filesize = 30M > did not work since I got an error 401
searched more and found this setting post_max_size as indicated by other users, set that and working with no issues now

If you using the linuxserver git the file to modify will be in

volumes:
  - /path/to/appdata/config:/config
  
   containername/php/php-local.ini

#php-local.ini content
; Edit this file to override php.ini directives and restart the container

date.timezone = Africa/Johannesburg
upload_max_filesize = 30M
post_max_size = 30M

I tried every solution provided here and I am still unable to change the background image, short of swapping out the app default background image file with another one.

I have max file and post sizes set to 100M in php.ini and max execution time set to 360.

Did you use the correct config file?

[lazarus477]

@B1GWH1T3 I cannot recall having edited/modified any config file during the setup of Heimdall. When going back through the documentation at: https://github.com/linuxserver/Heimdall, I noticed this;

Installing

...
"If you find you can't change the background make sure php_fileinfo is enabled in your php.ini. I believe it should be by default, but one user came across the issue on a windows system."
...

Now I am looking into the possibility that I am missing a PHP module.

[lazarus477]

From what I can tell the PHP module fileinfo is not available in the regular arch repositories but provided through Aur. So I do not have fileinfo installed and configured for use. This could explain my issue.

Current experience:
I can choose to change the background in the dashboard setting. Doing so opens up a file manager, I select the image file (jpg) and it 's thumbnail is shown. I press save. When presented with the dashboard all I see is a plain background color. Going back to the settings I can still see the thumbnail of my uploaded image, it has just not replaced the default.
