  Hi,

  Can you please post your application.log here? You can send it to me directly. Or you can copy/past here only the part that shows the error/exception.

  Best,

  Kristian

  Trying to download the application-log.gz file also results in a 404 Not Found error. =/

  That is strange. Your application.log filename is strange. You are on Windows 11? Can you tell me what files are in your logs folder? It's in the JATOS installation folder.

  Yes, I'm on Windows 11. Ahh, sorry, I didn't think about looking into the actual logs folder.. There actually is a text document and this compressed folder, which also contains a log text document.

  I'll send the content to you directly..

  In the log are some errors, e.g.

  2026-06-10 14:50:03,070 [INFO] - gui_access - POST /jatos/import/studyConfirmed (admin)
  2026-06-10 14:50:03,187 [INFO] - g.ErrorHandler - JatosGuiException during call POST /jatos/import/studyConfirmed: Couldn't generate path to file or directory "d5d60e31-db4a-4c0d-ba68-934b457ea74a".
  2026-06-10 14:51:58,828 [INFO] - g.ErrorHandler - Bad request: Cannot parse parameter studyId as Long: For input string: "test"
  

  and

  2026-06-10 14:56:18,516 [INFO] - gui_access - POST /jatos/study (admin)
  2026-06-10 14:56:18,684 [INFO] - g.ErrorHandler - POST /jatos/study - Couldn't generate path to file or directory "8be8ce32-bada-410f-90e7-71c250cde171".
  

  and

  2026-06-10 16:00:40,990 [INFO] - api_access - GET /jatos/api/v1/admin/logs/application.log?limit=-1&reverse=true (admin)
  2026-06-10 16:00:40,991 [INFO] - g.ErrorHandler - HttpException during call GET /jatos/api/v1/admin/logs/application.log?limit=-1&reverse=true: Log file not found
  

  They all hint at a problem with the file system access.

  I checked on a Windows 11 and could replicate the issue. The issue seems to affect Windows only (not Mac OS or Linux). I'll debug to figure out what is going on and provide a fix as soon as possible.
