After selecting the form on the submissions page, this loads and then I get this error: Fatal error: Uncaught Error: Call to undefined function ctype_digit() in /wp-content/plugins/ninja-forms/includes/Admin/Menus/Submissions.php:322 Stack trace: #0 /wp-includes/class-wp-hook.php(324): NF_Admin_Menus_Submissions->table_filter(Object(WP_Query)) #1 /wp-includes/class-wp-hook.php(348): WP_Hook->apply_filters(”, Array) #2 /wp-includes/plugin.php(565): WP_Hook->do_action(Array) #3 /wp-includes/class-wp-query.php(1140): do_action_ref_array(‘parse_query’, Array) #4 /wp-includes/class-wp-query.php(1868): WP_Query->parse_query() #5 /wp-includes/class-wp-query.php(3852): WP_Query->get_posts() #6 /wp-i in /wp-content/plugins/ninja-forms/includes/Admin/Menus/Submissions.php on line 322
I did click on the Show Legacy Submissions Page in the settings based on the other thread that was started. I also updated to WordPress 6.6. What do I do to fix the above error?
