NON-RESPONSIVE PAGE

Hi. I was designing one page and suddenly the content of it disappeared and since then everytime I want to look at it, now empty page, everything stops working. I cant work in the editor whatsover and have to restart it each time. I tried deleting the faulty page but it doesn´t work, it gets stuck again and again. My site is www.englishfun4all.com and the faulty page is https://www.englishfun4all.com/copy-of-online-activities I can´t even disable it as not to be find on Google. Please help me. Thank you.
