I tried to install the free version of WP quiz, but is will not activated. Each time i try I get an error message.
Plugin could not be activated because it triggered a fatal error.
Fatal error: Cannot declare class PW_CMB2_Field_Select2, because the name is already in use in [site url plugins folder] wp-content/plugins/wp-quiz/includes/libs/cmb-field-select2/cmb-field-select2.php
Any ideas?
