Layout stretched across page

Our website is http://semper.uqu.com.au/

The layout has suddenly gone weird and is now stretched across the page and the sidebar is now in the area where the footer is. Can anyone help please?!

Hi @semper,

I hope you are well today and thank you for your question.

I visited your shared site and it’s displaying fine for me as shown in the attached screenshot as shown in the attached screenshot.

Is it working fine for you now?

Best Regards,
Movin
