First off, apologies if a similar question has been answered recently. One of the sidebars on my site (http://www.jasondike.co.uk) has a sidebar which seems to be stuck in the center of the page, regardless of which theme I choose. Does anyone know how to fix this?
Best bet would be to start over. Go to your Admin => Presentation => Edit CSS and scroll to the bottom where it says (View Stylesheet). That is the default stylesheet for your theme. Copy the contents of that file and then clear out what you have in your CSS portion of your sheet with that file information. Then use the “Start from scratch and just use this” and save it. If there are a few things that you added for CSS, keep track of them with an offline editor (notepad or text editor) and then add them back in 1 at a time after you get it back to square.
