[Plugin: Infinite-Scroll] Mobile subdomain – Script not loading, 404 not found error

First – great plugin! Thought this would be particularly useful for mobile applications so have decided to try and use it on my new mobile website.

I got everything working perfectly on my live server, but now it’s transferred to my live web server the infinitescroll.init.js.php is failing to load and is returning a GET (cancelled) error due to a 404 Not Found error.

I can’t figure out why this would be happening but seems like it might be linked to the cookie settings?

I am running the ‘mobile-domain’ plugin (http://wordpress.org/extend/plugins/mobile-domain/plugin) to redirect mobile users to an ‘m.’ subdomain. I thought this might be causing conflicts, so tried disabling it and setting the mobile theme as the main website theme, but the same error occurred – the script won’t fire. Therefore, it doesn’t seem to be a plugin conflict.
The only other thing I can think of, is that I’m running WordPress 3.3.2 on my test rig, and 3.4.1 on the liver server, so perhaps it’s a compatibility issue?

I setup a custom function to call infinite scroll on the portfolio list pages of my site:
http://m.bml-creative.co.uk/our-work. Like I mentioned, the script is being called OK, but it’s just not running.

It’s not a game killer, as the page navigation works fine, but it’s a shame not to have it working as I think it makes a big difference to the usability. Any advice on what might be causing the issue and how to overcome it would be greatly appreciated.

Ps. I’ve enabled debugging!
