I am using WordPress 2.8.3 and here is the problem. WordPress is not allowing me to to save the post as Draft, nor letting me Publish the post. When I click any one the these button, I am redirected to "Nothing found" page on my blog. Here is the screenshot just to clarify.
Any idea what needs to be done? Since I am not a PHP expert, if there is a problem that you believe will fix it, please elaborate.
