Look at this validation report.
1. Scroll down to the html, look at line 13 to 21. The remnants of the script, a legal notice, the URL of the script provider, etc. are still there. You need to delete them.
2. Look at the number of markup errors. Either clear them. The sidebar and other problems may be over.
3. Use firebug with FF and correct CSS that can reset your sidebar in its position.
