What may cause the text of a message created with the Message module to be empty? I have installed the Message module to log activities, and set it up following these instructions.

All steps look good, and message (admin/content/message) is created after I added new content. But, the message's TEXT field is empty.

Also, Message: Render message (Get text) field in related View is also empty, and SHOW NO RESULTS BEHAVIOR is triggered.

I enabled message_example module come with message, same result.

Is there anything wrong with my options?
This is a rather typical issue in multi-language sites. A variation (not duplicate) of your question is what is described in "Rules - Set language of message notification".

A possible solution (work-around?) is what you wrote in your own comment below your question, i.e.:


  I checked Message class, and it turns out that I have a wrong language code, 'cause I set administer language to English other than default language. It works now after I set language back to default.


Another solution is to indicate the language in which the message is to be created.
