These are the error messages:
- When I try to backup a course: Fatal error: Call to undefined function backup_mod_selected() in ...\mod\assignment\backuplib.php on line 35
- When I try to restore a couse: Fatal error: Call to undefined function restore_userdata_selected() in ...\mod\chat\restorelib.php on line 65
I just did an upgrade of moodle to 1.5.4 from 1.5.3. The last time I did an upgrade of moodle I got the same mesagge every time for each module, I fixed them one by one just copying the backuplib.php and the restorelib.php from the last version of moodle I had previously installed.
