moodle 2.2 error tryin to restore a course

Hi! I have a problem that is driving me crazy. Wanting to restore a backup in Moodle 2.2 from the repository (also tried uploading the file) fails me: "This file is bigger than the maximum size"

 I changed php.ini  (post max size and upload max size to 128 mb and rebooted) I Changed the Site policies to 128 mb.  I don't now what else i can do... the file size is about 10 mb but I can restore the course .... any suggestions????
