Database creation fails

In CyberPanel v2.1 (on Ubuntu 18) I have previously installed WordPress successfully on sub-domain using the app installer. Now after a few months I tried the install on a domain and the WP files were downloaded but the database creation failed.

I then tried creating a MySql database in CyberPanel and that failed. I tried the same in PhpMyAdmin and it failed. However I can’t find any error logs on the server with related error messages.

CyberPanel is running on Php 7.2 (which needs updating) and the domain is on 7.4, and the extensions lsphp72-mysql and lsphp74-mysql are both showing in CyberPanel > PHP > Install Extensions as ‘Installed’.

Any advice as where to look next please?

Please show me the my.cnf file content.

etc/mysql/my.cnf

# MariaDB-specific config file.
# Read by /etc/mysql/my.cnf

[client]
# Default is Latin1, if you need UTF-8 set this (also in server section)
#default-character-set = utf8 

[mysqld]
#
# * Character sets
# 
# Default is Latin1, if you need UTF-8 set all this (also in client section)
#
#character-set-server  = utf8 
#collation-server      = utf8_general_ci 
#character_set_server   = utf8 
#collation_server       = utf8_general_ci 
# Import all .cnf files from configuration directory
!includedir /etc/mysql/mariadb.conf.d/

Contents of /etc/mysql/mariadb.conf.d/

I’ve just found this error in the main CyberPanel log:

"You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '-web' at line 1")[createDatabase]

The domain includes a hyphen, it’s something-web.ext, hence ‘-web’ in the error. Something similar here. Maybe CyberPanel is trying to create the database name with the hyphen and it’s being rejected? I wonder if this is fixed in v2.1 build 2 (current is v2.1 build 1)?

Yes I can create a database manually in CyberPanel and PhpMyAdmin if the database name excludes the hyphen!

Can you please check if mysql root user password is not changed.
check setting.py and cat /etc/cyberpanel/mysqlPassword
and this is same

No root mysql password NOT changed!

If I manually create a database after the failed WP install, the database name and user name are prefixed with the first 4 characters of the domain name plus an underscore. However the database name and user name in wp_config (created by the WP app install) have NO prefix, so navigating to the domain shows a database connection error. If I add the prefix then I see the WP install page.

run CyberPanel update command once and try or open a ticket we will check
