WebGL incorrect header check bug again in latest Beta?

Hello,
I use the Unity 5 beta 21 (the most current at the time of writing) for publishing the WebGL content.
Even after repeated attempts I get the "famous" error "Uncaught incorrect header check".
Tried on IE 11 and Chrome 51.

The same happened with the previous beta 20 (haven't tried before that).
As this bug was claimed to be resolved long ago, is it possible it has been reintroduced again?

The WebGL content itself is very simple - just few textured objects... the link is:
http://www.spg.cz/ivan/xpokus/glpotvor/

If the content is run from a local host (it means "Build & Run" in Build settings), it shows up ok; if the published files are then uploaded and viewed from the server, the error message "Uncaught..." appears.

Any ideas?

Ivan K.

 

Hello Alex,
thanks for the quick reaction and valuable advice - now it works, exactly as you described!

Maybe it would be useful to even put a small note into the Manual so users would not bug you again in the future - something like "...if you see the message ´Uncaught incorrect header...´, do not get scared and just adjust the mime-type..."

Thanks again

 

Hello alexsuvorov,
I have windows server 2012 r2 with IIS 7. I have tried this but my files are not running. Can you take a look and suggest more on this https://moodle.gaia-tech.com/downloads/maths/.

 

Code (CSharp):

1.   var Module = {
2.     TOTAL_MEMORY: 268435456,
3.     errorhandler: null,            // arguments: err, url, line. This function must return 'true' if the error is handled, otherwise 'false'
4.     compatibilitycheck: null,
5.     dataUrl: "Release/.data",
6.     codeUrl: "Release/.js",
7.     memUrl: "Release/.mem",
8.    
9.   };
10.  

The file name is not present .....

 

New issue : UnityLoader.js 404 not found. But i have that file.

Now i have 500m internal server error. Can you please help me on this. Please suggest me ASAP.

 

This is a common issue for people who start using IIS, as it does not serve files without associated handlers by default (unlike, for example, Apache).​

However, I'm getting this issue on Apache/2.4.18 (Ubuntu) and I don't know what I'm supposed to do.
