[issue] Buttons don't link after click

Hi, I’ve tried Safari and Google Chrome but the buttons I linked to another page doesn’t respond in Preview and Publish. Does anyone know what’s wrong?

here’s the link https://yifeiwang9119.editorx.io/yifeiwangportfolio

On checking, it seems that nothing is working on the site and nothing seems to be clicking or allowing to highlight text.

I see you have a ticket open with customer care so will include my findings to that case.
