When trying to upload a thumbnail there is constant error “Upload Image failed” "Thumbnail should be the following formats: .*jpeg, *.png, *.bmp and not exceed 3MB in size. I tried multiple thumnails that are all Under 1.9 MB and all PNG and they all do not work, I try with many previous thumbnails that I uploaded before no problem but now they do not work. It is a bug that need to be fixed.
Expected behavior
What should happen is the thumbnail you upload should upload normally and not give Upload image failed error.
