Site was live now it's down!

Hi there everyone, I’m in a bit of a pickle. We launched our site without any issues, however, after launching we obviously noticed a few pieces of copy that needed to be updated. After updating thta copy and publishing again the entire site is down. This is the error message I’m receiving.

Please help!

Here is my site Read-Only: LINK

Have you solved this ?

@JanneWassberg yes thank you so much. I forgot to take this post down last night.
