I have been having trrouble with k2 for three days.
Can anyone HELP me?

First the added items display the wrong author, then the Iframe modal pop up feature on frontend fails. Adding items is a full page interface.

So I upgrade, still no iframe and now I get a blank page when trying to edit front or backend.

I cannot trash or delete anything. It might be a java problem but by now I have no idea of what to do.

Is anyone here???
