The entire website went bold

I have recently been updating the content of my website. Then, the font of the entire website turn to bold automatically. I try to search for open HTML tag but no luck. There is not option for my WordPress to select auto correcting of HTML code either. What should I do now? Thanks.

The website I need help with is: https://www.mmu.edu.my/foe/

FYI, I have delete every pages and the recent posts 1 by 1, but still not solved. I suspect it is not due to the content that I have updated.

Hi, and welcome to the SitePoint forums! It looks like an issue with the Poppins font to me. Double check the way you are loading that font on your pages, as they seem to be defaulting to a bolder version of the font only.
