Using Moodle v1.9.13, plugin version v1.4.1.
There is also a bug in the plugin.
In the mdl_globalmessages_rules table, the 'rightside' field content is not always saved, resulting an empty field.
This happens when I create a condition (between 2 dates):
|1||IF||Date||Greater than or equal to||saturday, 2 february 2013|
|2||AND||Date||Less than or equal to||tuesday, 5 february 2013|
Please test creation of this condition, and check the values of the 'rightside' field.
Also note, that the plugin is not displaying any messages, if there is no rule created. I think messages should be displayed even, if there is no any rule created.
Please fix these bugs.
