New sidebar shows above content

Hello

I know sidebar issues are one of the most commonly asked about topics: apologies for asking about it again.

I had the same issue as PurplesRealm (https://www.ads-software.com/support/topic/229785?replies=5) and followed the instructions to add another column. The column appeared, and I was very pleased with myself – and you guys for the help.

However, the content and right sidebar appear underneath the new left sidebar. How can I make the content wrap so it all appears at the right height? I have added up the margin, padding and width of my elements and that all looks fine. I’ve also looked for missing </div> until my eyes have gone funny. This is the most advanced CSS modification I have tried to do, so you can tell I’m not expert.

My site is https://www.pm4girls.elizabeth-harrin.com. Don’t even think of looking at it in IE, it’s a mess.

Thanks in advance for any help.

EDIT: My theme is not widget ready. I made it so yesterday, thinking having two dynamic sidebars would help the issue, but it made it worse (not sure if that is the ancient theme or my coding skills) so I undid it this morning.
