Hi Markus,
There is some defects in a file: /plugins/code-snippetqs/php/class-list-table.php
Some functions of derived classe Code_Snippets_List_Table are marked as protected whether it should be public as in base class. Thoses functions modifiers should be changed from protected to public:
- get_views
- get_bulk_actions
- get_sortable_columns
- get_table_classes
- extra_tablenav
For example, use this code:
public function extra_tablenav( $which ) {
instead of:
protected function extra_tablenav( $which ) {
