Using WordPress 3.0.5 (read too many error posts about 3.1, so didn't upgrade).
Theme: Twenty-Ten
Firefox and IE
http://my-neighborhoods.net
This morning my right column on my homepage showed up at the bottom of the page.
I did edit the styles.css page, but did not touch any DIV elements.
Double-checked all of my comments tags /* */ but all are in pairs.
Things were working fine until some automatic updates.
All of my pages are one-column except the homepage.
I had altered the Portfolio page by increasing the width to accommodate contents.
Can't think or find anything else.
Thanks in advance!
