on installing new MOODLE 2.3
I get this error:
DDL sql execution error
It is usually not possible to recover from errors triggered during installation, you may need to create a new database or use a different database prefix if you want to retry the installation.
Debug info: ALTER command denied to user 'xxxx'@'localhost' for table 'mdl_config'
ALTER TABLE mdl_config COMMENT='Moodle configuration variables'
Error code: ddlexecuteerror
