Corrupted 5.1.3 Libraries after power failure

Hi,
Where is that folder located?

I have the same error after I did add memcached, my error message aren’t comming up all the time - just some time and started after I did add memcached, but I have rebooted the server now so let’s se if that helps.
My error is:

2017-11-02 20:49:09,069 [ERROR] django.request:256 handle_uncaught_exception Internal Server Error: /api2/account/info/
