XML request error: OK (200) Different problem...

I have exactly the same problem. When i try to open /ckfinder/ckfinder.html in Explorer 8 the following message appears:
Server response:
Status: 200
Response text:
Content-Type:text/xml; charset=utf-8<?xml version="1.0" encoding="utf-8"?><Connector><Error number="0" /><ConnectorInfo enabled="true" s="" c="" thumbsEnabled="false"

Have anybody an idea what's going wrong here?

Thanks in advance!

hello,

i've got a similar problem. after a fresh install of ckfinder i got a an errormessage with a timeout error (the php script exceeds 30 seconds). and after this i sometimes got the xml request error (200) and sometimes xml request error (12152)

got a linux server,
Apache/2.0.59,
PHP/5.2.1
mysql 5.0.36

any ideas?
regards olaf

-------- edit -------
i think i have an idea:
on my server there are two php extensions on my virtual hosts installed:
espeedboat (for speeding up php i think)
suhosin (security improvements)
i turned espeedboat of and it seems to work now...
I will watch that and let you know

Having problems getting CKFinder to display anything in folders view - swapped out from firefox to IE and I now seem to be getting the same error as you folks. I know CKFinder is unsupported until purchased, but why can would you purchase it if it doesn't work in the demo mode? Is anybody from CKSource going to address this issue?

I just solved my own problem.

Basically if I put ANYTHING in config.php that looks anywhere near session cookies BANG XML error 200. If I just return true (hideous security issues) then it works fine... great!

I confirm websanity's discovery. Can't call my session handler, which makes the security feature practically worthless. Serious bug.

Hi everyone,

I'm really sorry for late reply, it seems we have a problem here, we'll fix it soon.
