As in title mysql server is working. I can access it can create databases and run queries from phpmyadmin but when I'm trying to create database in control panel it shows it there but doesn't do anything on mymysql server. It's Ubuntu installation it was warking before. I have created about 10 other sites and all of them works just fine. Only change done since last database creation was movinig control panel to ssl. Tried to change this back but did not help.
Looks as if you have changed the mysql root password, this caused ispconfig to not have the permissions anymore to create databases. Please set the new mysql root password in the file /usr/local/ispconfig/server/lib/mysql_clientdb.conf
it's ok now. Did not change anything and it started to work again. I think it's mu test server rather then ispconfig.
