bad display of individual job

I use WP 3.5.1
Theme is Custom Community 1.12.2
Job Manager 0.7.20

There is a display problem that was not there before I updated to the last WP version. The display of individual job (listing is fine) appears at the bottom of the page, instead of next to the sidebar.

example: https://rssmo.qc.ca/emplois/intervenant-jeunesse/

Any input on how to solve this?
Thank you.
