HI
I installed K2 on Joomla 2.5 but every time I save an artical the page gives and error and jumps to 404.

The artical saves ok. but I have to back button to get back to the admin on the site.

It does not matter if it is a new artical or I just open a blank artical that I have already saved. when I resave I get the error.

If I open of creat a normal joomla artical I do not get any error.

Please help. I will have to uninstall as I can not find a solution anywhere.
