I am very happy with the Folders plugin, because it helps me to keep things organized and to find them quickly. But recently I had to install the “Ultimate Learning Pro” plugin. Some important features of this plugin don’t work if “Folders” is active. For instance, if I try to visualize the Courses list, the system shows this message:
Fatal error: Uncaught ArgumentCountError: Too few arguments to function WCP_Folders::output_list_table_filters(), 1 passed in /home/customer/www/zeninthecity.org/public_html/wp-includes/class-wp-hook.php on line 308 and exactly 2 expected in /home/customer/www/zeninthecity.org/public_html/wp-content/plugins/folders/includes/folders.class.php:2212 Stack trace: #0 /home/customer/www/zeninthecity.org/public_html/wp-includes/class-wp-hook.php(308): WCP_Folders->output_list_table_filters(‘ulp_course’) #1 /home/customer/www/zeninthecity.org/public_html/wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters(NULL, Array) #2 /home/customer/www/zeninthecity.org/public_html/wp-includes/plugin.php(517): WP_Hook->do_action(Array) #3 /home/customer/www/zeninthecity.org/public_html/wp-content/plugins/indeed-learning-pro/classes/Abstracts/Indeed_List_Table.class.php(190): do_action(‘restrict_manage…’, ‘ulp_course’) #4 /home/customer/www/zeninthecity.org/public_html/wp-content/plugins/indeed-learning-pro/classes/Abstracts/Indeed_Lis in /home/customer/www/zeninthecity.org/public_html/wp-content/plugins/folders/includes/folders.class.php on line 2212
