Error when loading site

Frappe Framework Website

I gotten this error when loading my site:

Don’t panic. It’s not you, it’s us.
Most likely, our engineers are updating the code, and it should take a minute for the new code to load into memory.

Checking the supervisor status:

Fixed this by backing up the sql and reinstalling from scratch

Your existing processes have not been closed cleanly (this happens when you close a bench tab without hitting ctrl+c)

try

killall -m python
killall -m redis

If you don’t have killall install it!
