Domoticz

I followed these instructions to create and uplod custom icons.
ZIP file generated, content look identical to what it should be in the instructions.
However when I select and upload nothing happens.
I used these instructions before and everything worked like explained in the wiki.
This time it doesn't and I cannot find the reason why.
There is nothing in the log.

Post the zip file here, or post the link to it, so we can check it!

Check the attached file :
you have to put in the same directory, for example
Volvo.png (16px)
Volvo48_On.png (48px)
Volvo48_Off.png (48px)
icons.txt
and zip those files into Volvo.zip to submit to Domoticz.

You got all files, but "Domoticz.png" is empty, 0KB

• Domoticz.png
  Domoticz48_On.png
  Domoticz48_Off.png
  icons.txt

I have used it lately, I used a graphics program and made a16x16 pixels of the image fil myself, just renamed it "domoticz.png" and dropped it into the zip file containing the other icons, replacing the faulty one.

3 out of 4 files is OK, just "missing" the small one..

The above file names are just an example..

Mm..
I downloaded Ziggo.zip from the examples to make shure it isn't the file that is corrupt or something.
Nope, I can upload it, it doesn't give a warning and still nothing.
BTW Even tried it in a Domoticz install on Windows..... nothing.

There are other custom icons installed, so in the past installation has completed without a problem.

EDIT 15 minutes later
Surprise!
In my case the icons don't install on Domoticz running on Windows, the icons don't install on Domoticz running on RPI3+ on bookworm , the icons install smoothly on Domoticz running on RPI4 on bullseye.
