I'm running CKFinder 2.3 (with a license) with PHP 5.3.2 on Ubuntu Lucid and I'm getting an XML error on load. I would normally suspect a server-side problem, but it works in some browsers but not others. It works fine in Safari (Mac & Win), IE, and Opera, but Chrome (22) and Firefox (15) give an error when loading the top level folder (the default view), and occasionally (but not always) when fetching the folder list:
It was not possible to load the XML response from the web server. The server returned an empty response. XML Parsing Error: no element found Location: https://www.example.net/ckfinder/ckfinder.html?action=js&func=ShowFileInfo&dts=1&id=ckf1 Line Number 1, Column 1
Using debug tools, I can see that the requests are identical (obviously different ones for GetFolders, GetFiles and ShowFileInfo) across browsers, but the responses vary.
Requests are to places like:
I've tried clearing my session, clearing caches, restarting browsers and apache, but still get the same problem. My config.php syntax is fine, `php -l` reports it's ok.
There are no errors being logged by apache, and nothing appears in responses if I enable error display.
