Ei!

any very novice at K2. I had installed it on Joomla 1.7 and whan I try create/edit an "item" I go to "Image" tab, and I press button to find throw the server, and appears the message:If I press "Select a file" at "Image item" and save the item, it appear a blank page (without code).
At the "Multimedia Manager" of K2 I get the same error.

I found a lot of information about another message very similar but with "Is not JSON" or something like this, and the solution that I try doesn't work.

Could any one help me?
I attach a caption on the error



thanks
Víctor
