[PlayerParticles] Data handler connected using MySQL.
[13:13:18] [Craft Scheduler Thread - 6 - PlayerParticles/ERROR]: [PlayerParticles] An error occurred executing a MySQL query: Unable to create or change a table without a primary key, when the system variable 'sql_require_primary_key' is set. Add a primary key to the table or unset this variable to avoid this message. Note that tables without a primary key can cause performance problems in row-based replication, so please consult your DBA before changing this setting.
