GK_contact no sent info

Hi, when i send a message , any information about sent message, or error, is displayed.
An error message is showed about JFile: :read: Unable to open file: /home/mydomain/public_html/components/com_k2/js/k2.js?v2.6.8&sitepath=/,
(fixed excluding k2.js from the compression)
Any idea?

Thank you

Please check if changing template to default Beeze helps.

I found the problem.
The div message container is below of menu bar (i use a fixed menu bar).
The strange is some messages show it correctly.
Anyway, the problem is solved.
Thank you.

Ok, thanks for the info.
