Leticia,
When is the error message displayed? When a teacher clicks on the Send in my latest ratings button? Using moodle 1.9, logged in as Admin, with debug mode set on, when I click on that button I get a different error message, this PHP Notice:
Notice: Undefined property: stdClass::$cmidnumber in ...\moodle\mod\glossary\lib.php on line 385
Ratings saved
and then the Ratings are saved.
Reported as MDL-14303.

Hi Joseph,
thanks for answering.
Yeah, I have that when admin or teacher click on the button Send in my latest rates...
The message about missing ID is displayed and nothing is saved 
How do I check if debug mode is on?
Don't know what to do... I'll take a look in the MDL though.

Just for the record, I'm using my own scale... I'll run some tests to see if it happens if I'm using standard scales.
I updated glossay module and it's working fine now!
