Error when editing user (QA Visitor) question while logged in as admin

Hi - I get the following error when, as admin (both Editor and/or Admin privileges) having clicked the link contained in an email that gets sent to me advising me that a user has asked a new question. The question appears in my browser, but when I click on 'Edit' I get the following error message...

Warning: require_once(/home2/designcom/clients/FloodAustralia/FAQ/wp-content/plugins/qa/default-templates/edit-.php): failed to open stream: No such file or directory in /home2/designcom/clients/FloodAustralia/FAQ/wp-includes/template.php on line 441 Fatal error: require_once(): Failed opening required '/home2/designcom/clients/FloodAustralia/FAQ/wp-content/plugins/qa/default-templates/edit-.php' (include_path='.:disappointed:usr/share/php:disappointed:usr/share/pear') in /home2/designcom/clients/FloodAustralia/FAQ/wp-includes/template.php on line 441

Clearly it should be opening the template file 'edit-question.php', not 'edit-.php'.
