I’ve been looking around a bit and I have found what the problem is, but not what the cause is.
Open the page (in wordpress) –>open firebug –> click on body –> click on edit:
Right at the top is a "." (fullstop). Once you delete that, everything jumps back up. The problem is that I can’t find where this is actually coming from, but it’s a step in the right direction :)
Did you use the starkers theme and create it from scratch, or edit the default?
Thanks. I used a slightly modified version of Chris’s BLANK theme. It’s really a weird problem, and I have this in my other themes as well and I fixed by using Negative Margins.
Any help will be appreciated.
