Hi Eugene !

No, that is not solution. You should never run cqrlog as root !!!

You just give enough rights for the database user you use for cqrlog database connection so that it can create,delete and use database.
Log in to your external database as administrator and give command:

GRANT ALL PRIVILEGES ON *.* TO 'cqrlog'@'%' IDENTIFIED BY 'cqrlog';

Change user "cqrlog" and password "cqrlog" ones you want to use.
Note that that this will give full rights to do ANYTHING on this database server. You can start with that, but I suggest you limit user rights if you are using database server also for other databases than cqrlog. If cqrlog is the only usage then this is ok.

When rights are set cqrlog can create all needed databases by itself.

When you again start cqrlog as normal linux user you may have errors. That is because you have used sudo for running cqrlog.
I have never tested what happens with sudo. Does it make all its files to user directory or to /root directory.
If it uses user directory with sudo then you must give console command:

sudo chown -R username.username /home/username/.config/cqrlog

Replace "username" with your linux regular user's username. That command will change ownership of cqrlog files back to your normal user.
Command will do no harm you can do it in any case despite it is needed or not to be sure that all files of cqrlog are owned by regular user.
