There are several problems with my journal site, http://www.ejtcs.org
1) I am using OJS 3.0 Alpha 1, and I cannot upload any image document (the image file is a JPG with 880 KB) at Management -> Website Settings -> Appearance, and add image button does not work. Dragging the file will upload it, but the system shows that no image file was uploaded.The error was: "No file uploaded or invalid file type". I could see the progress of upload, but eventually it is not very helpful nor successful.
2) Is it about the beta version of the software? Our webmaster decided to install this version, which looks great, and I would love to provide additional data to make it operational. Our journal has not started yet.
