My site is gone

I have worked on a site for 2 hours now, the last update was a script in the footer, automatically update the Year, and now all site are blank.

Is for a client and I should deliver tomorrow, so it's pretty urgent

Please help!
Thanks, Melanie

Have you tried removing the recently added code? My guess is that you are missing, or have an error in the closing script tag.

Thank you @Ziggy, now I now more than before. 🤩 The Site is here again.
