I’m running Win 10 Pro, and we typically use Google Chrome as our browser. In this instance though I forgot to mention that we received the same result on Chrome, Mozilla, IE, and Edge. Every browser had the same result.
We typically go to Media > Add New > Choose File > Upload
When she does this, there is no error or anything that pops up. After hitting Upload it just automatically goes to the Media Library, but her file is not listed.
