Added statement (binlog_format=ROW) to my.ncf and rebooted. I am still getting the same errors:
Error writing to database
Debug info:
Cannot execute statement: impossible to write to binary log since
BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine
limited to row-based logging. InnoDB is limited to row-logging when
transaction isolation level is READ COMMITTED or READ UNCOMMITTED.
DELETE FROM mdl_files WHERE id = ?
[array (
0 => '2345',
)]
Error code: dmlwriteexception
