For some reason the formatting on my blog suddenly messed up and one of my posts is now showing up where my sidebar is supposed to be. When I click on the preview button in the edit post area the blog shows up fine, but when I go to the published blog my sidebar is not showing up. HELP!
This is most often caused by an open HTML tag in one of your posts. It can also be caused if you are copying and pasting from the web or another application on your computer.
Go to settings > writing and select “WordPress should correct invalidly nested XHTML automatically” and then click “save changes.”
Now, starting with your latest post, open it in the editor, switch from the visual tab to the HTML tab (waiting for the page to refresh) and then switch back to the visual tag (again waiting for it to refresh), and then click “update post.” Check your blog and if it is back to normal, you are golden. If not, open the next post and do the same thing till it goes back to normal.
