Cannot upload file to a community forum
In Safari Version 9.0.1 (9537.86.2.7.2), I tried to upload a photo to a community forum but it does not upload. The first time I tried to do this with another photo in this particular forum I had success. I have followed all the website's restrictions for file size and dimensions. As a test, I created a simple file "test.jpg" that is only 966 bytes and has dimensions of only 58x39 but I get a message that the file is not a valid format. Any suggestions? Thank you.
