Fatal Error Help!

Hello,

I was trying to change some coding on my website through the editor. I originally pasted some code from this forum for eliminating the title pop-up from the image slider and it did not work. So, I tried to delete the code and after I hit “Update” an error message came back (entered the error message in the Private Content field).

This message is showing up everywhere now. Even when I try to load the website.

Please help! I am not a developer.

Thanks!
