Ok, this is weird and I'm not sure how to resolve it. I am the creator of LogZilla (a syslog management/reporting tool). One of my users has pointed out a bug that only exists in IE9. IE 8 and below has never worked properly so I can live with that. But IE9 should be working. FWIW, I am running IE10 and it works. But if I put it in IE9 mode it doesn't.
If you visit my demo server and do a search (just click the search button at the bottom of the page after logging in), you can see that the data is presented properly using Chrome and FF and IE10, but if you use IE9 it says there is no data to display.
I've also noticed that if you use a GET instead of a POST it works properly. The results page after a search has a small disk icon at the top right - if you click that you can get the full URL to paste as a GET.
I'm wondering if the problem is this which led me to this, but I have tried loading json2.js in the header and it doesn't fix anything (maybe I did it wrong?)
Edit: I also though Modernizr might help, but I have no clue how to implement it, and the download page is insanely confusing - which options do I need?
Edit: Based on @thatidiotguy's comment, I checked my source and it is actually using a GET, not a POST. So now I'm even more confused as to why pasting the url works when clicking the button from the main page doesn't?
