Hello,
After upgrade to 3.12.0, system check warns about missing files:
plugins/Morpheus/icons/dist/brand/Krüger_Matz.png
plugins/Morpheus/icons/dist/brand/öwn.png
I do understand that I can fix that on my system but I believe non-ascii characters should not be used in files names of such a popular product 
Good luck
Hi,
Okay, this one is on me.
I assumed that in a day and age where most software uses UTF-8 out of the box, databases can store over 100000 different characters and some programing languages allow using emoji in variables, using an umlaut in a filename wasn’t a that weird concept.
It turns out I am wrong and this will be reverted in
Thanks for reporting!
Hello,
Tried with the above changed files. Still the same issue persists. Following error is thrown:
File size mismatch: /plugins/DevicesDetection/functions.php (expected length: 10747, found: 10739)
Missing file: /plugins/Morpheus/icons/dist/brand/Krüger_Matz.png
Missing file: /plugins/Morpheus/icons/dist/brand/öwn.png .
Its because of missing entry in manifest.inc.php.
Hi,
This is to be expected as you would also need to modify the config/manifest.inc.php as it contains the reference the matomo integrity checker checks against.
You could also just ignore those warnings until the next release.
