Problem with K2 items and Problem with MusiCity template

Hello,

I am having the two following problems:

1) With all the templates I downloaded (The News II, Musicity,etc..) when I try to edit and article I got a blank page once I click on SAVE. And consequently the modifications are not saved.
I looked at your forum and couldn't find a similar topic

2) Yesterday I downloaded the Musicity template (Quickstart 2.5).
I installed it properly without any issue.
But when I clicked on the main news I received a pop up login applet asking me to provide the user name and the password
<<A username and password are being requested by http://project.gavick.com. The site says: "GK Staff Only">>
http://www.washiwara.com/index.php

Please see attached screen shots.

Please help me.

Thanks
Sam

2. Can You please show me a screen of such behaviour ?
