I was using regulas, and the right column was showing on my second page fine, but on the default home page, It would show up on the bottom, and not on the right hand side. Like the Right margin was set at 3/4 of the page, therefore the 2nd column would not fit.
You have HTML garbage galore within your posts. I have a feeling that you’re using the rich editor and you’re not closing out your tags. You’re going to need to switch to the regular text editor and then take a look at your posts to see what junk is in there.
