Yes, Martin, you are right!
I downloaded Moodle 1.1.1. but only installed it on my test server. "Forgot" to install it on Production. And those problems were in the Production site. Oops, sorry.
After using the latest english language package (of 21 of November), I don't get errors anymore. Thanks, it's solved.
I really like this module! And thanks to you guys for being so active. You answered my question in just one day, Incredible!!!!!
