Do you mean the one in column 'Initiator'? That shows quite a few lines of code starting with

/*! jQuery v1.8.3 jquery.com | jquery.org/license */
(function(e, t) {
function _(e) {
var t = M[e] = {};
return v.each(e.split(y), function(e, n) {
t[n] = !0
}),
t
}
function H(e, n, r) {

Do you want it all?

On the list of the requests on the left click on the first.
Then click on the response tab like this screenshot imgur.com/a/Ipdrv

Exactly.
Something is breaking the response and it is coming empty.
Are you using any security extensions?

Furthermore are you using K2's latest version? You can try the DEV version as well which includes an update to elFinder.
You can backup and install it from here: github.com/getk2/k2

We are using K2 2.7.1, which is the newest version and was released on Aug 4th.
We do not currently have any security extensions, but I am thinking about it.
I am a bit uneasy about trying the dev version, unless you have another hint before.
Today I heard that another user does not have these problems so far.

Yes, I never this issue myself but there are so many setups so a misconfiguration on the mime types, disabling symlinks, wrong permissions can cause issues.

The DEV version is safe but to be extra careful, you can backup before you update.

It worked! I have 2.7.2 [Dev Build] now.
How can I thank you? Hope you are paid well!

One add-on question: will I have problems upgrading from this build?

I am :)

You won't have any issues updating to the stable version once it has been released.

I am having the same issue. I have K2 version K2 v2.6.9 . THis thread is quiet old and I am not sure if solution found last year are still valid. Also, this seems to be a bug are there patches or am I missing a version? Any assistance would be most helpful.

Are you getting any JS errors?
Furthermore 2.6.9 is a bit outdated, 2.7.1 is the latest version and 2.8.0 is on the works.
