I would say that it's nice to know about making sure the url is correct, but there are still issues with the software.
Uploading - the process shows that the file is uploading, gets to the end and indicates that it was successful, automatically forwards you to the "Files" page where you see "0" for the file size. I can check on the server through FTP and see that, in fact, there is no file that has been uploaded.
It seems to me that the program has a problem with permissions. The program has been set to the defaults, meaning I'm not trying to use any different folder for upload but what the software uses by default. Yet, the files cannot be uploaded through the software - as intended and expected. Instead, the only way to successfully upload files is through FTP.
