Stucked to English WebGUI, no switching to German

Hi,

one of the last update of OMV fixed my WebGUI to English. Even when I choose German, after clicking into Username-field resets the login to English. After login I can select the another language, but it still stays on English.

I did the usual tricks, empty browser cache, private mode and it doesn't matter which browser or whether to come from Windows or Linux, all the same.

System: HP gen8 µS, OMV 2.2.5, bare metal, no raid, Docker, mySQL, Virtual Box and the normal stuff like Samba aso.

Any help would be appreciated.
Erik

Danke für den Hinweis,
das war so ziemlich die erste Maßnahme, die ich versucht habe und im private mode gibt es eh keine alten cookies.
Da auch von allen möglichen Browsern der gleiche Fehler auftrat, kann es m.E daran nicht liegen.

Sonstige Hiweise?

Problem is still present.
No idea what to check or where to fix?

... and with the update to 2.2.6 the problem disappeard. Silent as it came, it went.
I have no idea whether it was the omv-core or nginx or whatever.
If someone in the back did some work, thanks for this.
