Form submission and image upload errors

Hi there, sorry to be a pest again :D

I have encountered something strange with my review form submission - actually two things but they could be connected.

The form is set so public can submit, and seems to work fine. I get the message: "The article was edited but it will be published after approving by the moderator." BUT below this message the following displays:

jform Array

(

[title] => test 2 by judah raine

[category] => Array

    (

        [0] => 10

    )

            (

            )

    )

[section_id] => 2

[type_id] => 3

[id] => 

)

I've certainly never seen that before!!!

Also, the image uploaded (I'm using the gallery field) does not "save", as in when as reviewer I log in and open the article to edit, there is no cover image.

This is the form prior to save and close:

and this is the same field in the same article when I open to edit:

Could it be the the js file is scrambled? Don't want to fiddle with it if not, but it's the only thing I can think of.

Your input and advice would be appreciated, thank you
