Hi Admin!! I installed the new version (on the old version) in the  Moodle 2.9.1. Now, when I click on the course's attendance the system show the message below:

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@metrocampadistancia.eadprof.com.br and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

Can you help me?

thanks
