This processing error could appear when creating a module, but in this case it’s possible that it will also appear trying to perform some other actions, such as editing local components. We might find this error message as well: “Could not be created, processing error”. This is due to a MySQL configuration parameter, sql_mode. It has to be set in non strict mode, by adding to the my.cnf file:
[mysqld] sql_mode=""
Now, restart the MySQL service, /etc/init.d/mysql restart, and verify that the mode has been properly set:
mysql -u root -p select @@GLOBAL.sql_mode;
This should have solved any previous issues, and the parameter will remain properly configured in order to avoid future problems.
