Recorder - Mysql with some error

Hello!

I was getting the good old Error during query: (sqlite3.OperationalError) database is locked error.
I found this post about a possible fix. I blindly just copy pasted everything step by step.
Soo… its not working and this is the error i get in Hass

ERROR (MainThread) [aiohttp.server] Error handling request

Any idea how to fix it?
