Hello, 

I am new to Itch.Io and game developing. I have a game created in Unity that I build it with WebGL settings. I have followed several tutorials to upload my file to itch.io and have been successful in uploading it. However, when I go to Run the Game, it does not load the program. When I checked the console it says "Failed to load resource: the server responded with a status of 403" and is related to the "loader.js" file. Does anyone has encountered this problem? Does anyone has a solution or any advice for this? 

Thank you very much!!!!!

Please check the HTML guide’s section about common issues, there’s mention of what the 403 error means:

https://itch.io/docs/creators/html5#common-pitfalls

• Using aboslute paths instead of relative paths — Your project is hosted on a subdirectory on our HTML5 CDN. If you use an absolute path in your sourcecode then the file your are trying to reference will not be found. This is commonly associated with a net::ERR_ABORTED 403 error in Chrome. Absolute paths are paths that start with a /. Try using relative paths instead.
• Mismatched cases when referencing files — The server that hosts your project’s files is case-sensitive. MacOS and Windows computers allow for files to be loaded case-insensitive. It’s possible your project works locally on your computer but fails after you upload it. Please check that all files you reference use the exact case that is shown on your file manager. This is commonly associated with a net::ERR_ABORTED 403 error in Chrome. If you have a file named Hello.png, you must reference it as Hello.png, things like hello.png and HELLO.png will not work because the case does not match.
