Sidebar Not Working

Hi All-

I’ve had the Attitude theme installed for several weeks now and am very pleased. For some reason, this past week the right sidebar has been showing up as a second footer, and even after resetting the default design options under the themes tab it won’t go back to normal. I haven’t messed with the CSS code, and can’t figure out how to get it to go back to normal.

Here’s my website: https://www.lyndaturet.com

Any advice?
