I have three assignments that need upgrading from assignments 2.2, with the helper, but we are getting this error below?
Coding error detected, it must be fixed by a programmer: moodle_database::get_in_or_equal() does not accept empty arrays
Moodle 2.5.1+, Windows 2008 R2, IIS7.5, MySQL 5.1
Please 'Turn the debugging on' at your moodle site from Administration > Site administration > Development > Debugging . Set it to developer level and display debug message to yes. Then again check the error you get some more detail about it. Post it here.
