559158 Fix Word Press Blog Admin Page. Cursor problem

I hired a programmer on Scriptlance to develop my site in Wordpress. The job was completed in February but I'm not getting the promised support to fix bugs. I have a Blog page, but in the Blog Manager page, the I cannot put the cursor in the "Blog Description" box to TYPE or Copy & Paste the Blog post. The cursor will go in the "Title" and "Blog Excerpt" box to type text, but not in the "Blog Description" box. I need the cursor to go in the BLOG DESCRIPTION box so I can type AND copy and paste. *** SEE ATTACHED SCREEN SHOT OF WORDPRESS BLOG ADMIN PAGE.
