I recently upgraded from 2.2.3 to 2.3.1 and I've got a weird problem. The admin section works fine in Safari (on Mac), but not in Firefox (3.0.10, same computer). I've cleared the cache, restarted, flushed the server cache, and even changed the "browser.cache.check_doc_frequency" Firefox setting so it will get a new version every time, and still it's not working.

The issue is when you click a page to edit it, the AJAX fires off and downloads the new editor window, but it never actually loads the content. The "loading" spinner just loads forever. If I reload the page, the page I clicked on loads up (I believe a cookie is dropped). So, it's like it's working... almost. I can use Firebug to look at the result returned from the server and it appears to be there.

Any ideas? A couple of other posts sound similar, but they were related to language settings or updating a file manager. I doubt that's the problem here as it works in one browser but not another.

Thanks in advance!

Good suggestion!

I just tried it, and am getting the same result.

I dug out my laptop running Linux, and Firefox is doing the same thing. The common denominator seems to be that I updated the Mac and my laptop to run Firefox 3.0.10 recently. I wonder if there is a bug related to that in one of the JS libraries that SilverStripe uses...?

The fact that I upgraded SilverStripe recently could just be a red herring.

We also use SilverStripe at work (although we only just got started, so there was no upgrade involved), and FF 3.0.10 works fine here. So, there must be something wonky with the other setup.

I had not tried deleting the cache files directly as I thought that's what ?flush=all did. I just went in and deleted it manually, and I still get the same result.

Actually, we're having another issue with our web host as well. It's possible this is related. I'll wait until they fix that before worrying about this problem any more.

Thanks for your suggestions!
