How to run mysql in xampp (error)?

Question

xampp

The devil pulled me to watch a video that showed how to enable logging of all database requests to the log:
https://www.youtube.com/watch?v=4haU7uAcRjs&featur...

After watching this video, I added to my.ini:
log = file_log .log

Stopped-started mysql - error. Removed this line to hell - an error.
