We are running Quiz 7.x-5.0-alpha2. Installed and quick checked all configurations and Question configuration worked. Then installed Quiz Image Target 7.x-4.4-beta2 and now get: Call to undefined function cloze_quiz_question_config() in .../public_html/sites/all/modules/quiz/question_types/quiz_question/quiz_question.module on line 453.

I changed the config function name in the image_target_question.module file and we no longer get the error.

I didn't make a patch because I think the current name will be necessary for earlier versions of Quiz and a new branch with compatibility notices may be required.
