I have a unity game that I have completed and have built. So I have 2 files, an HTML and a .unity3d. I have my personal website hosted from http://Bluehost.com. I'm using Concrete5 templates and trying to upload the files but everytime it says invalid file extension. I uploaded both files to the FTP via bluehost unlimited ftp transfer. Using the Concrete5 templates I'm able to type in the HTML file and get the unity player on the website, but when you want to play it gives an error saying it couldn't download the game files. I could use some help please! Thanks!
