Since a few days my file upload isn't working. In my opinion i didn't change anything. Is there any possibilty to check why my image cannot upload? I checked the response header of the image post and got "Invalid characters" but ist e normal file name xy.png and I got AllowedFileExtensions -> png.
Can I check what FileName is getting through? I alawys get this red dot which stands for file upload failed.
Thx for your help
