I have tried all the answers described here, but for me the issue was something else.

I got the same message "Reload to see all sources" in firebug, and the Chrome debugger didn't display anything in the sources tab as well. I saw that the debugger was working on other pages for my website, so the problem was the page itself and after hours of sequentially deleting everything I had in the page, all that remained was an 'img' tag.

It seems the src attribute should not contain "#", perhaps someone with a deeper understanding of HTML could explain this, but removing it has solved the problem for me.

Hopefully this will be of use to someone else as well.
