I found this: by innodb_lock_wait_timeout can be set at runtime with the SET GLOBAL or SET SESSION statement. Changing the GLOBAL setting requires privileges sufficient to set global system variables
Could you please tell me how can I fix it?
You need to speak with your hosting provider, this is not a PS related issue.
