Error: “A problem occurred when adding the module. Processing error”

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.
