Bug description
Hey everybody, I recently updated two of my instances from 25.0.5 to 26.0.0. I am using the linuxserver docker-nextcloud image. On both instances I had previously:
- disabled customized theming for individual users
- no, logo, no background / login image, no favicon etc.
- simply selected a plain background color.
Everything was working fine, update itself was without problems, but after the update both themes were resetted to default and I saw the default cloud background image. In one instance I could remedy this by simply disabling "disable individual design" and re-enabling it, the solid background color returned. But on the other instance, this did not work and now it always whows me a background picture that I had once selected a few months ago (but I had disabled it again and as I've said set a solid background color instead).
When I re-enable individual user design, I CAN deselect this picture again and select a solid background color in the user-based design settings area. BUT when I re-disable individual user designs, this ominous background picture re-appears. I tried deleting and resetting the background picture in the admin design-settings-area to no avail. When I select a background color, my browser shows the background color for like half a sec before this background pic is loaded. Cleared cache, tried it with a different browser, tried it with a different device, always the same.
This is my first issue, if you need any logs or anything please let me know.
Can I somehow reset the theming app?
Steps to reproduce
See above
Expected behavior
The background image should disappear and show a solid color instead after I delete the background picture by clicking on the trash bin icon in the admin design settings area. But as I've stated, it doesn't.

I am experiencing the same problem with 26.0.0. I can set a new background image, but after deleting it, the previous image is shown instead of the color. Workaround is to upload a 1x1px background image.
Experiencing with 26.0.1. Also inverted avatars for some reason. Though #37379 seems to resolve the latter.
So, I tried and I cannot reproduce, so I will ask for more input.
Currently, I have:
- Disabled user theming
- Removed the global theming background
- Changed the primary colour
And as a user, I do not see any background image, just the colour the admin have selected :thinking:
| Admin theming | User theming |
|---|---|
 |

AH! I was able to trigger something though, if you upload a custom image AND you delete it, it will still be displayed for users indeed :thinking:
Will fix asap
