 * Hi!
    I tried going to manage/posts and clicked on the title of the post I wanted
   to edit, and this is what I got:
 * Warning: require(Text/Diff.php) [function.require]: failed to open stream: No
   such file or directory in /usr/local/ndn/web/oneclicks/wordpress/wp-includes/
   wp-diff.php on line 4
 * Fatal error: require() [function.require]: Failed opening required ‘Text/Diff.
   php’ (include_path=’.:/usr/local/ndn/web/oneclicks/wordpress/wp-includes’) in/
   usr/local/ndn/web/oneclicks/wordpress/wp-includes/wp-diff.php on line 4
 * It does this for both posts I selected!
 * A little background information:
    1. I was able to edit earlier this morning 
   w/o a problem. 2. Earlier this morning, when I went to “view site” I noticed 
   that it had the option to “edit post”. I was concerned that anyone looking at
   the site could edit my post. So I deleting all of my cookies and internet files
   and history, and went to my site; I saw that the “edit post” option was not there.
   3. I added myself as an author, and I tried to change my name as admin so that
   it would appear not as “admin” but Anne-Marie.
 * That is all I did today between when I was able to edit my post and not.
    fyi:
   my URL is : blog.organizationquest.com
 * THANK YOU for anyone who can help!
