CF7 causes footer problems

CF7 makes my footer go fullwidth while the rest of the body remains normal. Also the ‘copyright’ background is gone.

When removing CF7 from the page it’s all good again.

Check here: Page with trouble

Check here: Page how it should be

Both use the same page template.

Any thoughts how i can solve this problem??

Thanks in advanced
