Page didn’t look as what is intended

In https://ubcmun.org/keynote-speakers/, a weird bug happened: There is a random search bar, side bar and a “Jweb Solutions” advertisement appearing in this page.

All I want in this page is the menu, the title “Keynote Speakers”, and the body of “Keynote Speakers” paragraph.

Any reasons that suggest the random appearance of this bug? And how to fix it?
