Problem 2:
Somethime when I click in the pic for view big, appear a error see the pic for details:

Problem 3
Sometimes the button “close” doesn´t appear….see pic:

Problem 4:
Sometimes when the button “close” appear doesn´t work, I mean DOESN´T close the pic, I need to refresh the web. ( this do not need pics it´s simple)

I said SOMETIMES, because not is always, now, I uninstall and reinstall the module, but the same problems still appear.
