For a few weeks now (10 - 12) I have not been able to upload pictures to Wikimedia Commons. I tried to find a solution to the problem in the forum for questions, but I also didn't find anything. It is increasingly suspected that the error is due to the Upload Wizard, which has now become very unstable. If nothing changes in the incorrect upload in the foreseeable future, many users will surely leave Wikimedia Commons.
Greetings in the hope that the upload error will be fixed soon
