Uploaded pictures are not shown

[outsch]

HI, I have tried multiple times to upload pictures, by FTP or by mutliple picture upload through phoca, to upload and publish pictures as I have done with many other pictures in past on page https://www.narrenzunft-schnabelgiere.de/bilder.
The picturee are technically uploaded, and I have beforehand created a respective subfolder (as I did in the past) and a specific category (as I did in the past), but they re not being shown in the website and also they do not appear in phoca's picture view when being filtered to the category I have assigned.
Als, when I did this in the past, the thumbnail creating appeared while thumbnails were created by phoca, but now, nothing happens. When I attempt to re-do this, phoca brings an error message telling that the picture already exist, and over FTP I can chekc they are there, but phoce does not publiush them anymore.
Has anyone some idea on what may be different now and how I could get phoca to work properly again?
This site runs on Joomla! 4.4.9 Stable.

Hi,
als allererstes immer die Frage: Ist denn die Miniaturbilderstellung in den Phoca Gallery Optionen wirklich aktiviert?
Backend --> Komponenten --> Phoca Gallery --> Kontrollzentrum --> Optionen --> Miniaturbilder --> Miniaturbilderstellung-Einstellungen --> Miniaturbilderstellung aktivieren=Ja

Freundliche Grüße,
Benno

Hi Benno,
danke für die schnelle Antwort. Und ja, die Erstellung ist aktiviert (Seitenweise Miniaturbilderstellung: Nein, Miniaturbilderstellung aktivieren: Ja)
