I just installed Community Quiz and when I click on the certificates to edit them, I get the following 500 error and the path for the error is /administrator/index.php?option=com_communityquiz&view=certificates

I have reinstalled the software and still get the same results.

An error has occurred.

500 Unknown column 'a.title' in 'field list' Unknown column 'a.published' in 'where clause'
