Uploading files to the media manager


I have just installed and started using ContentBox. Unfortunately, I am having difficulty using the file upload feature in the media manager.

If I drag and drop a file to a folder it works perfectly but when I click on the upload icon and choose a file from the file system it uploads but the rotating spinner and message “Uploading your file…” never goes away. Do I have a setting wrong or is this a known bug?

Thanks in advance.
