Website down

One minute it was working fine and the next I get an Error 500 in browser.

I checked the error.log and I see this at the bottom:

[error] 22130#0: *33 FastCGI sent in stderr: “PHP message: PHP Fatal error: Uncaught Error: Call to undefined function wp() in /var/www/ Stack trace: #0 /var/www/ require() #1 {main} thrown in /var/www/ on line 14” while reading response header from upstream, client:, server:, request: “GET /22222 HTTP/1.1”, upstream: “fastcgi://”, host: “

Any ideas?


Could you please try the command

ee stack status

ee stack restart

and provide the o/p.
