Default Failed to load resource scripts/signup.php

Up to now, I have been able to establish a connection to jabber with no qualms on the application I'm building. All of a sudden, I can't connect anymore and that problem has been persistent for over 24 hours now. I haven't changed any part of my code. When I checked the chrome error log for the hello script, I got the following error:

Failed to load resource scripts/signup.php

I'm not sure what that's supposed to mean since I don't even have a signup.php file in the scripts folder. This is the same scripts folder that contains the strophe and flxhr libraries. I do have a signup.php file in the server, but it is in no way connected to the hello.js script. When I click on the error string, it leads me to a page which displays a warning saying the webpage has a redireict loop. I'm confused

Maybe I should include my version of the hello files. Maybe someone can run them in their machine and see if they have they same problem. Thanks

I don't see anything obvious in the code. I suspect something may have changed with your web server.

What url are you using to get to your hello app? At what point do you see this error? When loading the original HTML? Only after initiating a connection?

Hey Jack, I also suspect that my web server is at fault here. The URL is http://caffiage.com/ludo/hello.php

I get the error as soon as the page loads.
