K2 problems

Hello.
I used the "Financial Business" template. (Same problems with K2 I had in Musicity template)
And now I faced with the following problems:

1) I can`t make new or editing available articles (from quickstart), because the "Save and Save &close" buttons don`t work. Nothing is happend when click on them.

2) In K2 back-end there is Notice: "Please install JoomlaWorks Simple Image Gallery Pro" plugin if you want to use the image gallery features of K2"
and "Please install JoomlaWorks AllVideos plugin if you want to use the full video features of K2 ".
And here I have a question: without this plugins I can`t to load images and videos?

3) Links from articles in NSP_color 1-4 don`t work, do not transferred to full article page. But in the search string there is: http://www.mysite.com/index.php/21-cat- ... icle-first.

Can anybody help me?
Thanks in advance.
PS:
version of K2 -v2.5.7
version of Joomla -v2.5.6

Hi

1. This is most probably connected with server settings. But you should look for help in K2 forum. Anyway paste server settings here so many I'll notice where problem can be.

2. Without this plugins you cannot have gallery and video. But no problem as mentioned should happen without it. Anyway both plugins are free, if you will not install a pro version.

3. This is a menu structure thing. Please see our documentation and a title NSP links are not working. You will find a solution.
