Thank you, you saved me a lot of work. I was about to reinstall and start from scratch. Thank you. Dreamweaver put a line of spaces after the page. I took it out and it fixed the problem.

When editing php files, it's best to use a good text editor like Notepad++ or Crimson Editor which won't put extra white space in the file.
