Fatal Error when opening a result

Hi

When I try to view the results from the survey I receive following message:

Fatal error: Uncaught TypeError: strpos(): Argument #1 ($haystack) must be of type string, array given in /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/shortcodes.php:210 Stack trace: #0 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/shortcodes.php(210): strpos() #1 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/class-wp-embed.php(71): do_shortcode() #2 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/question-types.php(1448): WP_Embed->run_shortcode() #3 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/template-variables.php(1356): qsm_question_title_func() #4 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/template-variables.php(1149): qmn_polar_display_on_resultspage() #5 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/template-variables.php(483): qsm_questions_answers_shortcode_to_text() #6 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/class-wp-hook.php(303): mlw_qmn_variable_question_answers() #7 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/plugin.php(189): WP_Hook->apply_filters() #8 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/admin/admin-results-details-page.php(295): apply_filters() #9 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-content/plugins/quiz-master-next/php/admin/admin-results-details-page.php(64): qsm_generate_results_details_tab() #10 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/class-wp-hook.php(303): qsm_generate_result_details() #11 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/class-wp-hook.php(327): WP_Hook->apply_filters() #12 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/plugin.php(470): WP_Hook->do_action() #13 /srv/www/vhosts/bierjournal.ch/httpdocs/wp-admin/admin.php(259): do_action() #14 {main}<strong> thrown in /srv/www/vhosts/bierjournal.ch/httpdocs/wp-includes/shortcodes.php on line 210

So I checked the file. On this line the funtion “has_shortcodes” starts:

/**
 * Whether the passed content contains the specified shortcode
 *
 * @since 3.6.0
 *
 * @global array $shortcode_tags
 *
 * @param string $content Content to search for shortcodes.
 * @param string $tag     Shortcode tag to check.
 * @return bool Whether the passed content contains the given shortcode.
 */
function has_shortcode( $content, $tag ) {
	
if ( false === strpos( $content, '[' ) ) {
		return false;
	}

	if ( shortcode_exists( $tag ) ) {
		preg_match_all( '/' . get_shortcode_regex() . '/', $content, $matches, PREG_SET_ORDER );
		if ( empty( $matches ) ) {
			return false;
		}

		foreach ( $matches as $shortcode ) {
			if ( $tag === $shortcode[2] ) {
				return true;
			} elseif ( ! empty( $shortcode[5] ) && has_shortcode( $shortcode[5], $tag ) ) {
				return true;
			}
		}
	}
	return false;
}

I have not used shortcodes actively. Nor am I a software engineer. Please help me to get the results. Otherwise all expenditure was for nothing.

Thanks
