Adding wasm MIME type

I checked the request in my browsers network log, and it says the chkbuild.wasm URL redirects to the /error.html page on your site. Taking a quick look at the files in the file manager, it doesn’t appear that the .wasm file exists on your account at all, so the error is most likely caused by a 404 Not Found error. And no amount of .htaccess coding is going to help you load a file that doesn’t exist.

Please try uploading the missing files. If that doesn’t work, please note this article as well:

Especially be sure to take note of the file size limit: files larger than 10 MB are automatically deleted.
