After I clicked the Auto-patch function of Defender, it deleted a file in my WP core. Now my website is not accessible. Please help to undo!
These are the changes made as seen in email from Defender.

I've finished scanning http://chemactiv.com for vulnerabilities and I found 2 issues that you should take a closer look at!
