Page formatting gone wrong

Backlight 4, 5 & 6 Support

This page https://lucnadeau.ca/Expos/ is a bilingual page. I just finished some limited corrections to the English version and the page’s format is all wrong!

I only edited the page copy/main copy text and the language button has gone from the left to the right side of the top of the page and all the rest is all mixed up. Not so on the French version.

What did I do wrong?

Something like this usually happens if there are syntax errors in the html. Most likely an unclosed div or something.

I can see p tags surrounding a closing </div> tag:
<p></div></p>
This is happening at the very end of the french section

Solved! Thank you
