The web has gone blank. I am getting this error message and this link:
There has been a critical error on this website. Check the site administrator’s email inbox for instructions.
Learn more about debugging in WordPress.
I have not received any restoration email (not spam either).
It was probably when trying to install a plugin or wordpress theme.
I want to restore the web to 24 hours ago, to be able to access again.
Help please, I feel totally lost with this.
