Just today I found one of my sites with this
ERROR: dbConnect() unable to connect to database server "localhost"
MySQL error 1045 - Access denied for user 'mysite_jamroom'@'localhost' (using password: YES)
I tried this but did not work: https://archive.jamroom.net/Jamroom4_Change_MySQL_Password
I guess because I have installed JR5..?
