Sidebar problem

Check your posts for very wide images or long strings of characters (like long words or URLs). They overflow the post area which can make the sidebar fall to the bottom of the page.

Thanks Maerk, I don’t think it’s that though; I haven’t got any images on the site and it doesn’t seem as though I have any long strings of characters, but this is happening on every post page!

I can’t work it out!

I’d check some of the validation errors. Most are more semantic in nature, but the last couple in this example caught my eye: https://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fwww.spam-blocker-online.com%2Fspam%2F27%2F

Start here:

(see the unclosed div at the end)

Thanks HandySolo and Moshu.
